There are very few windows based options for transcoding from a DVD to MPEG4 or H264 formats (even the ones for AVI extensions using XViD or the sort were bulky unintuitive and hard to use.), and of what there is is mostly shareware with a price tag undeserving of the software.
So, I was thankful when I found MediaFork.
The CLI is easy to use (though I would like to see some more options like audio normalization, for example). I enjoy the fact that it uses open source software and libraries, many of which I'm already familiar with, being a linux user as well.
I use a Creative Zen Vision:M, and all of my friends use iPod videos, and this software has been very handy for encoding DVD's in XVid/MP3 AVI format for my Zen, and MPEG4/AAC format for my iPod using friends.
So again, thanks for the great software!
