OK I have a hauppauge 1800 and a ATI Radeon 5670 hooked up with my computer. I got them both working brilliantly, I have been on the ATI Radeon 5xxx thread talking about all the problems and got them all resolved, so I got DTS-HD sound quality through my surround sound awesome! Boxee and Windows Media Center work awesomely!!! I got windows media center recording channels perfectly, me and my fiance' watched glee via the HTPC last night, LOOKED AWESOME in HD (use the qam tuner via the hauppauge to get some HD channel so I can record them)! But when she switched to watched NBC's parenthood (god i hate that show) the channel flickers? Its only NBC... how can I have everything correct but only NBC does not work. I can play video games, watch internet tv, watch CBS, FOX, etc but for some god awful reason NBC just flickers on and off almost like when I had auto-contrast on my Sharp television. I don't even know how to troubleshoot this!! I just told the fiance' to watch via the cable box until I figure this out for all the NBC shows (the Office, parenthood, parks and recreation). PLEASE HELP ME!
