Jay, I just remembered one other reason this can occur--but only in 
older versions of MythTV (including 0.26).  It will occur if you have 
ever run mythfilldatabase as different users on the system, due to reuse 
of the same directory name for caching the data.

The best fix is to upgrade to 0.27-fixes to have code where that's 
impossible.  The alternative is to remove all the temporary data 
mythfilldatabase writes out.  The easiest way to do this on most (all?) 
distros is to just reboot (and let the reboot clear out the /tmp 
directory structure for you).
