Hello all, I've been having a hard time getting any TV Tuner Cards to work in my current rig. Here are the Specs: AMD 3500+ ASUS A8N-SLI Deluxe 1 Gb Corsair DDR 400 XLPro 1X XFX 6800GT 2X WD 74 Gb Raptors NVRaid 0 WD 250 Gb PATA HD Sony DVD-Burner Sony DVD-Rom Antec Neo Power 480 PSU Cooler Master Centurion 5 Case Windows XP Pro SP2 So far I have tried two TV Tuner cards: Sapphire Theater 550 Pro Theatrix and Hauppauge WinTV-PVR 150 At first I blamed the problems with the ATI card on the cyberlink software that was included, but now I'm not sure. The Hauppauge card will not display video and there is no sound even though it searches and finds all the cable channels when it sets up. Here is a list of some of the things that I have already tried: 1.Enabled PCI Snoop palette in BIOS 2.Updated all drivers and BIOS 3.Downloaded updated software and codecs from manufacturer site. 4.Have also removed and reloaded drivers multiple times and rebooted The card shows up in device manager and says it is working properly (ha). If anyone knows about conflicts with any of my hardware or has any idea on how to fix this it would be most appreciated. Thanks in advance.
