I'm getting conflicting results when I search. I want to backup my movies. I've started using a program backing up to XviD, as noted in another thread in this forum http://forums.afterdawn.com/thread_view.cfm/326409 Basically, I want to do what is best as far as quality is concerned and would like to keep as many movies approx 1 1/2 to 1 3/4 hours long to about 750-800 megs. Movies which go into 2 hours or longer I normally compress down to about a gig or a little more. So, as a beginner, what is best for me? Should I go DivX or XviD codec?
