Jason:

I had exactly the same problem.  The issue is with the ATI drivers and it's
TV out support -- you will actually see some XVideo related errors in the
mythfrontend log when you try to switch to any video output in Myth.

Are you using the ati-fglrx drivers?  What does your xorg.conf look like?

I use the ati-fglrx drivers and here is the relevant section of my xorg
(this is for a PAL-B system...adjust accordingly).  Let me know if you need
further info/instructions:
