for the stills... i believe "grab" or "snapz pro" are two apps that let you take screen shots of the dvd while it's playing... so you could do it that way
but to get both qts and stills... it kinda depends on your level of experience. ideally you'd have quicktime pro (in fact, you pretty much have to have it... well worth the 30 bucks)...
and there are a few apps that would allow you to extract the tracks...
if you feel confident enough that i could email you the apps and you could use them and figure it out, then let me know via pm what your email address is... otherwise, search around versiontracker.
the 3 apps i use are "osex" which extracts the video/audio. then there's an app to convert the vob video file to a quicktime readable format... and something to convert the audio to aiff or whatever.
ps. it's a question of getting the mpeg 2 OFF the dvd... not just getting it into qt.. though i'm not sure that would work. and it's one more thing to buy.
