The Hauppauge WinTV PCI board provides television and radio input to a standard PC. This basic model provides PAL, NTSC and SECAM decoding with only mono sound. Other boards provide NICAM stereo as well.
After up- (or should that be down-) -grading to Windows XP it took several months to obtain a working driver. The supposed XP driver from Hauppages website fails to install with a "The data is invalid" error. Hauppauges Technical support people have been less than helpful in addressing the problem. I eventually found an item in their FAQ some months afterwards which addresses the problem - you need to change some of the permissions in the registry before installing the drivers - after which WinTV2000 works perfectly!.
