I am testing GBPVR on my PC. I have a wintv250 and ATI vidoe card. Everything seems fine except most of time GBPVR playback/liveTV has pixelation on the top of image (just a line across the top, barely notice, but annoying). I changed video card and no difference. On the other hand, playback on WinTV 2000 is ok and image is much more smooth. Any help is appreciated.
