Interesting... I'm not using the HD capabilities, but Comcast did give
me one of those HD boxes since we currently have their crap
Comcast-Tivo service (that I'm hoping to replace with my Mythbox).

Coincidentally, I wrote to the list yesterday about OSD's being
recorded in my Myth recordings, so this may inadvertently fix another
issue too!

Is there a postitive/negative to using S-Video from the Comcast box to
the capture card versus using a coax connection?
