I used a free utility(I forget the name but can get it) to convert my DVD's to AVI files so I can watch them on my mp3 player. The software only had DivX and one other codecs. I compress to 720x480 and got a file that was about 1.24gigs. Is that good or is there software that can do better. I would like to put as many movies on my micro SD cards as possible. I know I can decrease the resolution to get them below 1 gig but would like as good quality as possible.
