[QUOTE="rsbrux, post: 214153, member: 49539"] I cleared and rescanned the channels, but the symptoms are still the same. I'll try deleting and adding the cards, as you suggest, and scan again. Is there some way to adjust MP's scanning sensitivity? Hauppauge WinTV finds 49 channels (the correct number), whereas MP comes up with 82, which includes a lot of harmonics and sidebands. P.S. Is it possible that the problem is on the display side? This is the only thing that makes sense to me, since the channels show during scanning. P.P.S. I deleted both cards, re-added just the analog one and rescanned: no change. :( All channels show video and sound during the scan. None produce either in MP's TV mode. P.P.P.S. The problem is in the privileges. The account I used for configuration had admin privileges, the one I was running MP under had only power user privileges. Giving it admin privileges got TV working. Giving it full control over the directories involved, without admin privileges, wasn't enough. Why does MP need an account with admin privileges for TV? The privileges don't seem to be needed for the other functions. [/QUOTE]
