CinemaSix 1.3 oddness

I realize it's a "developers release", but i thought you might like 
some feedback.

I had something strange occur. , a dvd ripped to my Mac plays perfectly 
under 1.2, but in 1.3 when playing back a particular section, it will 
always skip to the ending credits. (It is several chapters from the 
end) in 1.2, it doesn't happen at all.

* When I say "perfectly" I mean almost perfectly.. a few lip sync 
issues occur.

Secondly, i've tried ripping "U2: Go Home, Live from Slane" using 
MacTheRipper as well as DVDBackup, no matter what it always plays back 
with no sound. Any ideas?

Thanks for the work on what could be the "killer app" for the HD1000!
