Travis:

In the CocoaDVDPlayer sample, Controller.m, function - (BOOL) 
isValidMedia:(NSString *)inPath folder:(FSRef *)fileRefP, I just 
returned YES from that method. It's not a very good solution, as it 
will try to open anything now, but I was able to get it to open a 
VIDEO_TS folder.

WRT this DVD api, are you talking about http://developer.apple.com/
documentation/GraphicsImaging/Reference/DVDPlaybackRef/index.html?

There's a function for setting a video port and device, which I think 
I can set to a gworld, but there are also functions for setting the 
display id and window number. Are these required to be set, since a 
gworld isn't going to have either?

Thanks,
