ratDVD

Great solution for archiving DVDs. The quality is very reasonable, ALL of the options are retained (if you want), and the filesize ends up usually being < 2GB. Very nice.

Now, I've only tried converting 2 DVDs so far, so I haven't really used it enough to have an informed opinion, but I can certainly say I'm impressed so far.

I've heard reports that the current version is buggy during playback and will crash or act oddly when you seek.

Looks like it is MPEG4 with a new container...
