odd, I have no issues with 7738, same video card, but Athlon64 3200+, no attempt to use XvMC, and I have no idea if I'm using OpenGL or not... is this with live TV or recordings? the combing you will see and is kinda inevitable if you output a 1080i signal via 720p. I imagine 1080i out via 1080i would not show the combing, though I'm not positive as I haven't the fascilities to test.
