I've recently built an HTPC for my family, specs are as follows:

AMD Phenom II x3 720 BE 2.8GHz with 4th core unlocked
ASUS M4A785TD-M EVO
4GB DDR3 1333mhz RAM
550W Gigabyte PSU
NVIDIA GeForce GT240
24x DVD Writer
Silverstone Grandia GD04B Chassis
Hauppauge Wintv HVR 3300 HD PCIe tri-band TV tuner


I have my system up and running and hooked up to our 50" Samsung Full HD tv. The tuner is working perfectly and the freeview channels are in HD like they should be. I have SKY Tv plugged into the card as well which is the NZ equivalent of satellite tv i guess. It receives the picture but its a bit blurry and not as good as when the box is plugged straight into the tv. Is there a way i can fine tune a tv card signal or something to get the quality of the picture up?

Thanks in advance :)
