I have a ATI 2600xt on a P4 machine running XP. Whenever I use the component (RGB) or svideo outs to play a video on the secondary display, the screen has tearing problems a couple times a second right in the middle of the display. My primary display is on a DVI connection and had no such issues when I moved the video window back to it.
At first I thought maybe the CPU was having trouble decoding high bitrate video content, but the same issue even happens when playing a DVD (easily less than 15% processor usage). I couldn't find an option in the Catalyst control panel to enable Vsync (one of the solutions mentioned online), but I did find a place to force 60hz refresh. It doesn't help. Any ideas or suggestions on what to try or if there is something I am overlooking?
