Sorry I missed the original post. The pcHDTV 3000 card has known problems with 
QAM tuning. Basically, the card is VERY finicky about what else is in the 
computer. Use the wrong video card, the wrong power supply, or possibly even 
the wrong motherboard and you'll get an incomplete data stream and possibly 
even an inability to tune the stations. Speculation I've seen is that the 
board relies on 5V voltage, IIRC, which is an uncommon requirement in modern 
PCI cards, and modern systems often don't deliver it in a stable enough 

That said, I have no idea if the same problem exists in the pcHDTV 5500. If it 
does, you may either be out of luck or be in for a lot of component swapping 
as you attempt to get something that works properly. Alternatively, you could 
trade in the pcHDTV card for something else. Before swapping hardware, 
though, I'd recommend you research the pcHDTV 5500's QAM reliability
