Great. That's pretty much what I thought was going on. My first set of patches boosted the signal quality by about 3 dB across the board, but introduced the edge case that you ran into. The last patch in the series fixed that issue. > Now to figure out how to integrate this stuff with Myth, including the fact > that several channels can be gotten in HD, digital SD, or NTSC.

Yeah, those are challenges that many users encounter, regardless of which card they are using. Good luck! Devin -- Devin J.
