rman, thanks for the input. Not sure what you mean by an X windows DVD application. But, playing the DVD on the G4 wouldn't be too bad, though. Actually, what I'm trying to do is be able to play 2 different region DVDs without hacking the drive. My G4 has two DVD drives, each set on a different region. The problem I'm having is that the G5 only has one slot for a DVD player so I can't take one out of the G4 and put it in there. I want to play the movie on the G5 only for the optical audio. If I'm interpreting you right, I can play DVDs using the G4 which would display on the G5 monitor? But this would mean the audio would be from the G4, yes? Thanks.
