OS X :: Mac Pro Freezes During Video Playback In Win7
Jun 15, 2009
I have a Mac Pro 1,1 with two displays and an NVIDIA 8800 card. I was booted into Windows 7 using bootcamp, the machine froze during video playback, hard rebooted. Blue Screened in Windows, went to restart into OS 10.5.7 and I get the Apple logo and spinning gear, it then flashes briefly and goes to a grey screen. The second monitor never engages. The machine is fully booted as I can connect to it with my laptop through filesharing. I've tried PRAM/SMC reset, removing all the RAM/all external devices, pretty much everything. I've even tried replacing the video card and switching PCI slots, with the same issue still occurring.

I added some 512 MB DDR2-FB DIMM 667 MHz to my Intel Mac Pro Dual Core - OS 10.4.11. Since the memory upgrade, videos will not stream properly in my web browser. The video begins playing; then freezes; audio continues for a few moments; then audio freezes; then beachball for a few moments; then video plays again; then the same cycle of video interruption begins all over again. It is consistent with YouTube, Vimeo, and basically any video format accessed through my browser.
Info:
Mac Pro, Mac OS X (10.4.11)

Latest quicktime + perian.
Tried reinstallling quicktime and no change.

For about a month now I noticed that whenever I'm watching a video on YouTube in HD or when I'm watching a movie trailer on Quicktime at 1080p, the playback lags. Prior to this everything worked well. All the videos I watched played smoothly at any resolution at any quality. I have an iMac with the following specs:
2.4GHz Intel Core 2 Duo
4 GB of DDR2 SDRRAM
ATI Radeon HD2600 Graphics Card with 256 VRAM
Also, I do not have many windows or applications open when I watch these videos. I have also close to 21GB of hard disk space used up out of about 280.

Have tried both quicktime and vlc, put video playback seems to be jerky on any panning shots on videos.
Have tried some 1080p trailers from the following link, especially apparent on the new ice age trailer.

I purchased it in June and have had this issue from the start. I am getting some artifacting/ghosting effects on the screen at times when watching videos. It happens 3-4 times during an hour or so of playback and resolves itself within a few seconds each time. The effect looks similar to that of poor encoding or something along those lines which is what I thought it was at first, until I tried playing videos that I knew for a fact didn't have this problem. The video pretty much freezes or colors get inverted in some areas, but the audio is not affected. Let me know if you need any additional details.

how well HD video plays back on their system?
I know that I'm not gonna be using it for 1080p content while I'm on the go, but I do have a lot of movies in 720p, as well as TV shows.

My current Mini (1.83 ghz dual) skips frames when playing back 1080P QT MOV files.
I use the Mini as a DVD player / HTPC. Only recently started taking 1080P video and was bummed at skips on big screen playback.
Has anyone tried playing 1080P video on the new 2.26 ghz model?

I have had my black macbook for a little over 2 years it is a c2d 2.16. It has ran flawlessly until recently it has been freezing during video playback. Mostly during online streaming like hulu or netflix. The screen usually gets these little red or green dots all over it when it happens. A couple times the the sound continued but usually it stops. What is going on? It has happened almost every day for a couple weeks now. I am running the latest version of OSX

I'm using a 15" 2.33 GHz Intel Core Duo Macbook Pro, with 3GB 667 Mhz DDR2 SDRAM, with Snow Leopard. Western Digital 320GB 7200 drive.
I've recently been having video playback issues, starting within Final Cut Pro. The clip will play fine at first but then stutter and freeze on and off. I have to constantly stop and play to get through it.

This is question is being posted in the Mac OS & System Software because I couldn't find Quicktime under Windows software. Quicktime Player works fine under XP Pro on one PC and my other XP Pro computer has Quicktime Pro. MOV video is washed out running with Quicktime Pro but also Realplayer's playback is washed out. All other image files display fine.
Info:
Quicktime Pro 7.7.1 1680.42, Windows XP Pro

When playing DVDs on the Apple Air USB DVD player, the video can get quite jumpy when the screen image is complex. Pans are especially challenging. This is when the computer is driving a 1920X1200 external monitor.

I recently upgraded to iLife 06. Now if I import a clip into iMovie, then apply, for example "fade in" at the start it results in jerky playback. It renders the whole program useless.

I'm currently running an old powermac G3 that's fine with everything except video playback.
My question, is it the 300mhz processor, the video card (stock ATI rage), or a combination of both?
Before it's said, I would buy a new computer if I could afford it.

I'm running Leopard with latest patches. Web browsing and other things are fine, its only video that is giving me problems

Just noticed that when I'm lying on the bed with my MBA on my legs, watching so [URL]videos....it starts skipping in about 10-15 minutes.
I don't see core shutdowns.....but actually the video/audio is going to desync and starts skipping....is this normal? Do I have to get a MB/MBP just to watch Hulu and flash videos?
I think this may be related to the temperature, but usually it's not that hot.

why are all my iTunes videos so damn choppy?! High Quality Youtube videos are "ok," but HD Youtube videos are just as bad as trying to watch anything on iTunes.
what do i need to upgrade (word choice?) to successfully watch iTunes videos crisply. i'm assuming it's like a graphics card or a processor or something. i could buy a decent computer in the next couple of months but i'm not because my parents are strongly against me upgrading anything because i'm going to college Fall 2010, so they said i'll just get a high-end something or other when the time comes. the point of what i just rambled about was is there something on my current PC that i can upgrade?

My current setup is: 2009 20" nvidia iMac, 4GB RAM/640 GB HDI generally would like to know what my expectations for decent video playback should be - thankful for any help people can offer on this:When using the Apple DVD player on full-screen mode, dvd playback seems quite grainy, with pixel lag on fast video sequences. Specifically, I was watching original DVD music concerts. The concerts were at night, so the picture is darker, but on my TV & stand-alone DVD player, the picture was less grainy and there was no 'pixel lag'. During computer playback no other programs were open, WLAN was off. The HD is empty except for Apple's stock software.So, could one or more of the following be a logical reason for grainy playback?:a) it's a computer, not a stand-alone DVD player hooked up to a TV.
b) screen quality: TN panel compared to CRT TV.
c) integrated graphics, i.e.: the 2008 iMac with dedicated ATI Radeon 2600 Pro card would be smoother.
d) display settings on Apple's DVD player. (using stock settings BTW)
e) full-screen mode performance is generally not perfect on any system.
f) none of these - something else entirely.

I often have 720p MKV video to watch, and I was wondering whether the current generation base model MacBook White is capable of playing them. I know that the MacBook White has the 9400m GPU which should be capable of doing it, but does it work in reality? What software do you need?

I am a new Mac user and so far I love it! My biggest concern is the quality of video playback when I am watching a DVD movie. On my Old HP laptop, the quality was far better. Is there an issue with playing DVD's, or does it have to do with the screen resolution of the MBP (1440x900)? As far as still pictures go, the screen looks great! Its just video that doesn't look the best...

I'm trying to figure this out and I've gone through 'Energy Saver' settings and turned off 'Put the hard disk(s) to sleep when possible' but sometimes - not reliably, playback of a video file just pauses and then resumes as normal after about 10 seconds. It happened just the same with QT and Perian under Leopard and now happens in Snow Leopard too. Similarly, this sort of oddness happens with playback on VLC too.

I'm wondering if anyone else has or is having issues with video, specifically music video, playback in iTunes. I noticed it when I was trying to play a video I'd downloaded, about 3 weeks ago. I'd bought the video some time ago, already have watched it several times before, but this time it didn't play. I didn't think much of it. But all of my other music videos did the same thing. From what I can tell, it's exclusive to music vids. My tv shows play fine, the few movies I've bought, etc. But not a single music vid plays back. It's just a screenshot of the video. I made a smart playlist, of all my music vids, versus tv/movies and there are 61 music vids and not a single one plays.
This was happening prior to the iTunes 9 update, but I'm not sure when exactly, or with which update it did start happening, as i just noticed about 3 weeks ago.

I have a powerbook g4 which has a screen resolution of 1280x854. Does that mean I can watch 720p content? Because adobe in terms of coding for mac is a big fail and won't let me watch anything above 480p with a steady frame rate, is this the same for non flash content?

So I bought a Sony Bloggie camera, and sprang for the extra $20 for the 360 video recording attachment. So sony touts on their website how great this camera and their software plays with Mac and PC, the truth is only the mobile dumbed down version of their software works on a Mac. The full version is PC only. unfortunately the full version is needed in order to convert and watch videos shot with the 360 attachment.
Fine no problem thats why man invented VMWARE. So I install the software on my windows XP virtual machine with XP sp3. The software converts the video but whenever I try to watch it the thing crashes and I get that report error to microsoft message. So my question is, are there any alternatives I can use preferably on Mac which will play the 360 video? I know a lot of websites have 360 virtual tour videos embedded.

I have a Rev A MBA but for the first time I just downloaded a TV show from Itunes and tried watching it back. It was very jumpy, freezing and video and audio were sometimes out of sync. I turned off all other applications, which improved it, but did not solve it. I tried downloading a second one and had the same problem.
Is this common? I would have thought of all applications to work well, Itunes should be one of them.
