I just bought realMyst a few days ago. The game seemed to be working fine at first, but after solving one of the first puzzles, I started watching Atrus' message to Catherine in the Cauldron and the video stopped playing halfway through. The video cuts off at a different spot every time I play it, and the other videos I've seen so far (the intro logos and the red and blue books), seem to play fine. Has anyone else had this problem? I'm using Windows XP, AMD Athlon 64 dual core, 2 GB ram and Geforce 8400GS.
