I keep getting an error message: Playback failed due to one of the following; 1) audio device in use or not installed. 2) Display overlap is not available. 3) Not enough video memory. I have tried everything I know to correct this, no luck. I am using an ATI Radeon PCI video board w/32Meg, Athlon 1.4, 512MB. I feel it should work ok, it doesn't. ATI's website had very little help also. I have tried 3 different players, Windows Player, ATI player, and HeroIII. The DVD's will play using HeroIII, but the picture is slow and the audio is also choppy. Not much to watch. If you have a possible solution please let me know.
