I'm currently in the process of writing a comparison of available DVD ripping programs for GNU/Linux. I picked the best contenders that I'm aware of and compared their features and ease of use. The goal was finding the best app for converting the main movie of a DVD to a single file playable on any computer and the winner is a surprising one (at least to me since I almost didn't include it). As a bonus I threw in a few apps targeted at creating DVD ISO's for burning back to a rewritable disk. Hopefully it will be ready to go within a week. Keep an eye on the News RSS feed for an announcement.
The apps I will be reviewing are:
I had also intended to review Drip, but it had unmet dependancies in Debian unstable and would not install.
