It seems to me that if the Mac can play DVD's through it's DVD playing programming it should be able to play VOB's, IFO's from a folder. I can't think of any of the commercially available PC based DVD playback programs that don't. WinDVD, PowerDVD, and TheaterTek all do. Of course, I'm an idiot when it comes to Mac's but it just seems like it should be "so".
