I tried it. It either works for you or doesn't. There doesn't seem to be an inbetween. It really is more of a beta product than something I would pay for. I have written their customer service several detailed emails and included terminal logs, only gotten one reply.

v1.0.1 worked for me but didn't playback in all DVD players and occasionally skipped but was fine if I backed up to the part missed.
v1.0.2 doesn't skip forward as much and works in both my DVD players but it has really bad artifacts and sound glitches.

v1.0.3 works in every DVD player I have been able to try (even my neighbors) but has sound glitches and some freezing.

It seems like they get one thing fixed and screw up others.
