Dtox
DTOX is DVD2OneX, the Mac version.
Sometimes people use it to get just the Movie, none of the extras.
Also, DTOX can sometimes fix the DVD's mastering errors that are purposely designed to make DVDs harder to copy.
I use DTOX to get just the main feature, and hand pick the audio tracks and subtitles, get rid of FBI warnings and previews.
Sometimes FairTox, Fairmount and DTOX is easier than using MTR. I prefer it. Also Ripit is turning out to be a great app.
