Your libraries and binaries don't match up.  You probably have parts of 
the ATrpms and part of the self-compiled MythTV on the system and in 
use.  Best bet is to clean off everything MythTV (from /usr and from 
/usr/local) and then install with one approach or the other.

That's a problem, too.  Fix it--upgrade the backend.  (It's not causing 
this issue, but will cause other issues.)
