Wow, that actually worked!  I unplugged the cable, rebooted, then 
plugged it back in.  The video looks great now.  I have my cable split 
and one feed goes to my cable box and the other to Myth.  When I unplug 
the cable from my computer it affects the picture on the cable box, so 
there must be some kind of interference on the line.  When the cable box 
was unplugged yesterday I think that interference messed up the card. 
As long as both boxes are plugged in there are no problems, though.
