I can confirm also that
DVDFab HDDecrypter 3.2.1.0 is working fine under Kubuntu Gutsy 7.10 with Wine 0.9.46, and
DVD Shrink has always played well for me. I have the restricted driver for my NVIDIA 6600 GT as well.
This is indeed great news, as I was looking for something to replace RipIt4Me when it becomes too outdated.
For background, I like my movies in xvid, to stream through my xbox, so I use this process:
RipIt4me (now dvdfab) --> DVD Shrink (to remove unnecessary audio streams, etc before avi conversion) --> AcidRip to convert the movie to xvid.
The resulting avi plays flawlessly on both my xbox, as well as in my stand-alone philips divx-certfied dvd player if I decide to burn to disc (love having th LOTR trilogy on 1 disc)
So for me, this is awesome.
