I need to make a persentation via powerpoint for my college class. I have a MAc and they have a Windows. What I have is several History movies and documentaries on DVD that I need to to grab parts out of and put them together into seperate .avi files for my Powerpoint presentation. I don't need the whole DVD (In fact I need about 1-2 chapters from 3 DVD's). I downloaded OSEx and FFMpegX, read up on DVD extraction and muxing and de muxing, etc etc. However I'm still lost and a bit confused. Can anyone just point me in the right direction on how to extract portions of a DVD and convert them into .avi files? I've tried for the last 3 days and I'm getting veeeeeery frustrated. Thank you.
