I know that this must be a really dumb question, but as a newbie maybe someone will have pity on me. I have a slew of movies eating up the disk space on my Apple IMAC which I can't burn to DVD because they are too large. I want to burn only the movie and audio files so that when I play a DVD, it begins to play without the menus and special features. My problem is that I don't understand what the individual video/audio files mean (VOB, AVI, etc.). I can't seem to find an understandable explanation anywhere. Does anyone know what these files mean or if it is possible to burn a DVD with only the necessary files (no menu/special features), or how to split these files between two disks so that the second disk will continue to play the movie. I presently have nearly 60Gigs of movies that I can't copy anywhere else to free up my disk space. My only option it to make viable DVD burns or delete them. Please help.
