Mac Mini :: Video Stops And Starts?

May 30, 2012

I'm really struggling to understand why my 2010 mini has trouble playing some QT videos that my 2006 mini handles just fine!  The two machines are: 

Macmini 1.1 (1.83 GHz)
intel Dual Core
Memory 2GB
Bus Speed: 667
Graphics Card GMA 950
VRAM: 64MB

[code]....

The problem first presented itself as I am working on a generative video installation using Max6.  I've used the older mini for the installations for some time with very few issues.  I've been using the newer mini for video processing, compression, and editing and making DVDs and blu-ray disks.  No issues there that I have noticed either.  However, when I recently tried to use the newer mini to run the generative video, I noticed that several of the videos were stopping and then starting up again (skipping).  I know that Max can sometimes have trouble with videos due to processing issues - but why would it work fine on the older, less powerful machine and only have issues on the newer one? 

To begin troubleshooting, I ran one of the videos in Quicktime on the newer mini to see if similar issues arose, and they do.  No problem on the older mini.  The video is formatted in DVCPRO50 anamorphic format, and I am using the same monitor in both cases (1440x900,60Hz), connected by VGA to the monitor PC input. I know that Quicktime can have similar issues with very large files sometimes, but I still don't see why the newer machine stumbles with the same video that runs fine on the older one. 

I've been hoping to start using higher resolution videos in this work, but am worried that if a newer machine can't handle these SD videos, HD will be worse.  I like the minis for installations because of their small size and portability.

Software :: Disk Permissions The Process Starts And Then Stops

Jun 1, 2008

When I attempt to verify or repair disk permissions the process starts and then stops. The following message appears in a drop down message box: First Aid failed. Disk Utility stopped verifying (repairing) on G4HD because the following error was encountered: no valid packages. My disk verifies in working order. I have used DU from the installer disk and obtained the same resulting error message. I have run Tech Tool Pro's optimization and maintenance sequences. I reinstalled Security Update 2008-003 PPC thinking it might have been the problem. This permissions verification/repair problem and a problem with my firewire external HD and iPod failing to mount started after I installed the security update. (I am not asking for help with the firewire drive problems here - that is for another forum) I am running 10.4.11 on a G4. I guess my next step is to reinstall 10.4.6, the version I bought

I have an Unibody MacBook. I've experienced that under OS X "Tap to Click" function of the trackpad stops to work after "some" usage. Then I go to System Preferences, disable the feature, reenable it and it starts working again. OS X is updated and firmware updates are all installed.

OS X :: Unable To Format External Hard Drive / Starts And Stops With Disk Error

Mar 24, 2009

I received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.

Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?

OS X :: EyeTV Stops Video On MBA After Few Minutes?

Oct 31, 2009

I just change a old MBA 1.6 GHz (OSX 10.6.1) for MBA 2.13 GHz (also OSX 10.6.1) and haven problem with EyeTV (3.2.1 version) via Pinacle Hibrid Stick 330e. Soft start excellent - I can see video for few minutes (3,4-5) and than video stops - audio is going (but only for next 2-3 minutes). To see something I have to restart soft or unplug an plug stick to USB port (I do not use HUB, I only use extension of USB cable - MBA have not so much space to plug directly Pinacle Stick). I have to say that on old MBA everything works fine, same OSX version, same USB extension cable, etc.). I try to see if soft and stick works on another computer - I use MacBook Black version (last black configuration) and results: no problems. Video do not stops! I try to find solution on macs forums but I did not find anybody who have this problem.

Mac Mini :: SD Card Stops Internet Connection?

Oct 14, 2010

I've had my (Mid 2010) Mac Mini for a few months now and been frustrated with intermittent WiFi connection (cuts out for no apparent reason and cannot connect to the router) I have other macs in the house so I know the network is working fine. Anyway, I noticed tonight that this only happens when an SD card is located into the slot on the back of the mini. So I played around with it for a while and as soon as the card is pushed in I lose my signal ? If I eject the card from the desktop nothing changes but as soon as I physically remove the card from the Mac Mini the WiFi connection is back and I can load internet pages again.

Applications :: Exporting To Quicktime From Keynote - Video Playback Stops?

Nov 26, 2009

I am running a Macbook 2.4GHz with 4GB of RAM and Snow Leopard.

I have an issue using Keynote 09.

I have created a presentation that has a m4v video playing in the background.

The video was the first thing I put in and was just placed on the slide and set to play when the presentatation starts.

The video starts at the beginning automatically and plays for the entirity of the presentation. The presentation is only 2 mins long. Over it are a number of different words all with various animations. There is also a music file playing in the background.

I have then recorded the show with manual timings and now when I play it in Keynote it runs smoothly from start to finish. The video continues to play and the transitions are smooth.

HOWEVER, when I then try and export the presentation as a Quicktime file I encounter a problem. The video starts initially at the beginning of the presentation but the minute any other animation kicks in the video freezes and does not restart. I have tried a large variety of export settings but to no avail. I have also spent time trawling the internet to try and solve this problem but no solution found.

It is very frustrating. I need to export it because I need it as a movile file rather than a keynote presentation.

OS X :: Keyboard Stops Working After Mac Mini Wakes From Sleep?

Aug 8, 2007

I have an obscure brand USB keyboard that I am trying to use with my Mac Mini, with one problem: after the Mini goes to sleep and wakes up again, the keyboard doesn't work. The solution is to either unplug and replug the keyboard or restart, but both are I think unnecessary hassles.

What I like even more is that the keyboard will wake the Mini (by pressing the spacebar or something), but won't work after that.

I also tried a plain ol' Apple keyboard, which works just fine after sleeping/waking.

Any ideas on what's going wrong, or how to fix it without replugging/restarting? It's just a keyboard, so I don't see why it should pose as any real problem after waking, so buying a new keyboard is not quite what I am looking for. I may end up doing it anyways (a wireless one to go with the wireless MX1000 I am using) but at the moment I don't want to spend money for a new keyboard.

It's a 1.66GHz Core Duo, 512MB RAM, 60GB HD, OS X 10.4.10.

OS X :: FFS - Fix Spotlight - Stops Playing - Miss Frames - Sound Gets Off Sync With Video

Aug 10, 2009

This is really really starting to annoy me now. I'm watching a movie, and suddenly out of no where, it starts stuttering. It stops playing, misses frames, sound gets off sync with video, overall kills the movie experience. Checking activity monitor, I see mds.app going crazy thrashing the hard drive. What the heck Apple. I don't need spotlight updated every 10 minutes. Is there a way to set times where it scans my computer? I rarely even use spotlight, most of the time I use it to launch programs. Plus, most recent files I really don't need to search since I know where I put them. Please Apple, add some more options for spotlight for heaven's sake. I looked into spotlight options and it's a pathetic splatter of simply selecting which folders you want it to *display*. I want to make it only index at twilight times, or only if I'm not using the data heavy programs like the video player. I don't really want it turn it off though, as I use it sometimes and it's been helpful in finding things. I don't know why Snow Leopard doesn't address this, since it seems like the same interface that's going in 10.6.

Mac Mini :: Unable To Get Display Via Tv / Connected Mini DVI To Video Adapter

Mar 28, 2009

Just a warning, I bought a Mac Mini (2009) and wanted it to hook it up to my TV. My TV does not have HDMI or DVI inputs so I bought a Mini DVI to Video adapter from Apple.But I could not get it to work, then I googled for it and it seems this adapter does not work with 2009 Mac's since it does not output an analog signal anymore!

URL

So anyone that wants to hook up his new Mac to an older TV set with the Video adapter, you are warned.I guess i'll have to buy a Mini-DVI to VGA adapter and then a VGA to SVIDEO converter..

OS X :: Command+tab Switching Stops Functioning / Shortcuts Stops Working

Nov 22, 2009

On a day-to-day basis I run: Adobe PS, INDD, and AI, Microsoft Entourage, Firefox and iTunes. Just recently, after an upgrade to Leopard, I added Things and Simplify Media to the list.The problem that happens before (on Tiger) and now (on Leopard) is command+tab switching stops functioning and Expose hot corners and shortcuts stop working.

I'm pretty sure this isn't a Finder crash because before, on Tiger, I could quit+restart Firefox and everything would be back to normal. Almost as if some shortcut had causes the system to act differently or there was some app dissonance?

But now, with Leopard, nothing I quit will cause these two features to act properly until I do a restart. Both features (command+tab switching and expose) are very necessary for my work flow. I have checked SysPref to make sure keyboard shortcuts are default and Univeral Access to make sure assisted devices is turned off.

Mac Mini :: New Mac Mini - Choppy Video Playback In VLC For Mkv Or Avi Files

Sep 30, 2010

Just bought the new mac mini with HDMI out - 2.66Ghz, 8 Gb RAM, 500 Gb HDD

A lot of mkv or avi files I playback appear pretty choppy in VLC - my primary app for watching movies and tv shows.

I have a Drobo with two 2 TB SATA drives where I store all my stuff and which is connected to my mini via firewire 800.

I've tried playing the same video back from both the Drobo and from the internal hard drive, to see if the choppiness was on account of the external drive or not. No difference really. A choppy video remains choppy from either place.

It's pretty strange because some 1080p videos play just fine, with no choppiness whatsoever, while other 720p videos or even standard definition divx files are still choppy.

Mac Mini :: Using Both Video Outputs

Apr 13, 2012

I am using both video outputs on the back of the mini, VGA and HDMI. Thes VGA is running to a projector and the HDMI is running to a computer monitor. I am also running Bootcamp WINDOWS 7. When I power up the Mac, the computer monitor goes to sleep and defaults to the projector as the main monitor. If I power on the projector first, before powering the computer on and then power the MAC on, it recongnizes the computer monitor as the default monitor. Why can't the MAC mini recognize the computer monitor(HDMI) as the default when both video outputs are connected?

Hardware :: Playing Video On The New Mac Mini?

Mar 4, 2009

I recently have gotten into video, such as downloading .mkv files from Vuze, and .mov and .avi files from various other places. Now that I will be purchasing a Mac mini I hope to watch movies from the iTunes Store. One of the things I hated about my Power Mac G4 500 is that it's slow processor could only play about 45 percent of the videos I had. The rest of the videos I tried either the audio and video would either out of sync, just sputter along, or refuse to play at all. Will the 2.0Ghz processor of the new Mac minis be sufficient for video, or do I need to go with the 2.26 Ghz processor offered in the "build-to-order" option?

Mac Mini :: Unable To Get Video Signal

Mar 16, 2009

I received my new mac mini last week and installed a few things on it over the weekend so that I can run it as an HTPC. Works great but I am having one issue and that is with the video signal. I have the mac mini connected to my Samsung 720p LCD TV with VGA using Apple's miniport to vga adaptor.

When the TV is already turned on and I start the mini or bring the mini out of sleep then everything works OK. However if the TV is off and I start the mini or bring it out of sleep and then turn on the TV, I get a "no video signal" message.

Mac Mini :: Powers Up But No Chime Or Video?

Nov 8, 2009

I have an '07 vintage (DVI) Mac Mini I use as a media center. I haven't used it in a few months & its been shut down during that time. I went to start it up today & the power light went on & I could hear the fan start up but no start-up chime & no video.

I did an PMU reset to no avail. I'm thinking the logic board is done (it's under warranty & I have an appt. with a "genius" tomorrow). Just wondering if there is anything else I should try before I bring it in.
