Thanks for all the help. I've been trying to get this to work for the past two weeks. I already had the latest version of Quicktime before I installed Riven DVD so I tried uninstalling it and then re-installing Riven and letting it install the version of Quicktime that comes with it. I am know at least able to play the game. The quality isn't that great and every now and then during one of the movies the screen turns completely white, which is annoying to say the least. I tried upgrading Quicktime to see if that helped at all but it just made Riven not work again.
If you have any idea how I can get it to work better please let me know. Hey! I just had a thought. Maybe it has something to do with the fact that in Quicktime 3(version with Riven) the program is called MoviePlayer.exe and in Quicktime 4(newest version) it is called QuickTimePlayer.exe. Maybe if I upgrade and then rename it. Huh, I'll have to check that out.
Thanks,
Teddy
