Correct...the problem occurs when I simply scan digital channels, much like you would if you were trying to program a new TV set with available channels in your area. As soon as I make the attempt to scan the channels, the program locks up. Specs: Vista64, Hauppage WinTV HVR-1800 capture card/tuner, Intel Quad Core Q6700, 4GB...VERY frustrating. Any help is greatly appreciated.
