Help I am pulling my hair out with my HTPC. It doesn't stutter in the DVB-t sofware that comes with the card and I have full signal strength. If you make a small window with the MCE TV playing it is fine but when I maxmise it I get stutter and blockyness. I had the same problem last week but when I turned Cool n Quiet off it went away. But now its back Any help would be great.
