(MacOS 10.2.6 on a TiBook.) I just VLC after spending over an hour trying to get Apple's dvd player to play a disc that kept causing dvd player to crash after the previews that the disc forces you to watch. I tried everything I could think of -- turning off extensions, rebooting, running nothing except dvd player, etc. So I tried VLC for the hell of it, and presto, not only did it run the disc flawlessly, but it enables operations like fast-forward that *didn't* work under Apple's dvd player. Fantastic! Thank you!
