The quality of native linux DVD ripping software sucks
compared to what is freely available on Windoze. Use
DVDFab or AnyDVD. You can rip to ISO or DVD directory
(i.e. VOB files). You can recode, compress, edit, etc.
You can also playback the DVD from file using any
DVD player app (e.g. VLC, PowerDVD, InterVideo, etc) and
you can stream video from hard drive to TV now.
Archiving your DVDs in AVI format is going backwards.
At the least use Wine to run the better Windoze ripping
software. »
