swasam, I am getting the exact same error! Do you think it could be due to the TV pack? Do you recall getting that error before the upgrade? I don't, but I also never tried getting QAM channels before the upgrade.
The analog channels are working great. I get 69 channels and cant seem to get rid of them. We are definately on to something here. Does anyone else have thse symptoms on other versions?
swasam, have you tried scanning digital channels in WinTV6?
