I put together a G4 Gigabit Ethernet from parts collected from around 
the world - eBay, Swap List, various merchants, and my basement 
stash.  I bought a CD-DVD Rom from OtherWorld Computing.  $30 
refurbished Matsushita SR-8582(Apple 2X DVD, 24X CD-Rom).  It does CD 
stuff just fine. What it does not do is play DVD's from Hollywood 
Video.  But it will play the only DVD I own - the one that came with 
Jim Heid's book - 'The Macintosh iLife'.  DVD Player fires up when I 
put in a dvd, but I get only a black screen.  Anything but 'eject' 
gets an error message or makes DVD Player lock up and quit.
I don't know enough about OS X to check out other drivers/extensions/whatever.
I'm running OS X 10.2.5  I just tried  in OS 9 and dvd's will play so 
the problem has to be something in OS X.
Anybody got any ideas?
