I have noticed when using the TV and Digital VCR function of MMC 7.1 (Radeon AIW), there is a strange left to right "wipe" of brightness that occurs every 1 second or so.

It DOES get into the captures, which can cause havoc with black or dark background (makes Star Trek really annoying to watch).

Has anyone suffered from this?

My specs (in case it helps):
P3 966
W2K
ATI Radeon AIW
Direct x 8 w/ DV update
MMC 7.1
latest shipping ATI drivers
connected to stand-alone Tivo

(granted, my guess is that the AIW is not having a good time with the Tivo, but I don't know)
