Have you attached a TV to the cable that goes into your MythTV box?  My
father has this on the CBS channel.  It's the strength of signal coming in
for that channel on the cable going to the MythTV box where it looks fine on
the TV upstairs.  Putting in different cable fixed it for him.  Ok I don't
know all the specs, he's the electrical person, but he has all these
different kind of cable, and rattle of something about the cable he put in
that fixed it.  Not gold plated or anything, it can just handle more
bandwidth or something.  I can ask him if you really want to know.

Now I had more than 1 channel, like 15 like this, what fixed it for me was a
signal booster.

Anyways, just my 2cents, YMMV
