My setup is the following: I split the coax output from my DirecTV receiver.
One output from the split goes straight into the tv. The other output from
the split goes into the mythtv box. The mythtv box then has s-video into the
tv. So, I can then switch between tv and Video1 to see differences in the
picture quality. 

I wonder if that coax splitter could be a source of problems. Tonight I'll
try feeding the output of the DirecTV receiver straight into the mythtv box
and see what happens.
