Applications :: Easiest DVD Screen Capture Method?

I've been having a remarkably difficult time finding a "quick and easy" method of doing precise and/or easy screen captures from a DVD.

Things I've tried:

VLC: Works, but recent builds have been crashing like crazy when playing DVDs, so are nearly unusable for that. (Anybody else been experiencing this?) Also lacks the ability to capture a precise frame, since there are no "step forward/back" controls.

MPlayer OSX Extended: Left to its own devices, can't handle playback of many commercial DVDs--it stops playing at the first title change, so is useless. If I use FairMount to unprotect the DVD I can play the .VOB files directly with it, which is semi-functional, but it also lacks precision--no single-frame step commands, and if you do a screencap when it's paused you actually get a frame or two later. Also, this leaves you guessing what part is in what .VOB file, and it chokes badly on multi-angle video.

DVD Player + screencap app: This also works, but I really just want the DVD frame, so I end up having to manually crop out the window border, which is time consuming.

My goal is to come up with a smooth enough workflow I can do, say, a half-dozen screencaps from a bunch of titles quickly, so my primary goal is efficiency. (It's for movie reviews, so it's even completely legal under fair use, if probably anti-DMCA due to the stupid encryption loophole). Secondary is to include deinterlacing and being able to more precisely select a frame.
