Unfortunately, it doesn't look like either of those are the problem. The
cable is firmly seated. I also tried a different cable. And, I have
another card that's going to go with a system I'm building for my wife.
That one's also having the same problem. So, that seems to narrow it
down to either software on the system (which seems a bit unlikely to me,
but what do I know?) or something about the receiver output that the
capture card doesn't like. The H20 is an HD DirecTV receiver, and in the
interface, it seems like you can't disable 480p. Could it be possibly
cycling between 480p and 480i? I can't imagine it would, considering
it's going over a S-Video cable and as such would cause similar issues
when hooked up to the TV.

Any ideas?
