HI, I've just bought a used HCPC and have found that when playing DVD's that there is a glitch every 30 seconds or so where the movie kind of fast forwards or jumps forward about a second or two. Anyone any idea what this could be? I'm going to update the Radeon driver to see if that helps. Any other things I could try? As it is, it's unwatchable and I've had to switch back to my DVD player. The graphics card is an ATi All-In-Wonder 7500 and the DVD player is a Pioneer DVD-106s and I'm using Power DVD 5.0 and Power Strip on XP. Thanks in advance for any help. Cal.
