Is there a peice of software similar to DVD Shrink that will do the same to AVI files downloaded from the net? Example, I can fit nearly a four hour copy of a dvd on to a single dvd-r but when I burn AVI files to a dvd-r I get only two hours max. Is there a way to compress these AVI files so I can get more on ond dvd-r? I use DVD Shrink and NeroVision Express to burn dvds. Thanks!
