Very good question.  :)  I don't think there's any way to get the 
cleanup without mfdb, but I have to admit I know nothing about EIT.

I would guess that all users should run mfdb--even those who have only 
specified video sources using "Transmitted guide only (EIT)".  For these 
users, mfdb wouldn't download data or populate the listings tables, but 
would perform the cleanup of old data.  However, at first glance, it 
looks like it might output a warning, "Grabbing XMLTV data using eitonly 
is not verified as working."  The warning is harmless (and running mfdb 
won't cause any problems), but if you get the warning, we should modify 
mfdb to handle eitonly better.  (If you try it out, please let me know 
if you get the warning in your log--direct evidence could save me a lot 
of digging into the code.  If that warning appears, I'll submit a patch 
to fix the warning.)

So, let me throw this out to the experts...  Is there any way for people 
who do not need to use mythfilldatabase to grab listings to get the 
clean-up functionality mfdb provides (in clearOldDBEntries() ) without 
running mfdb?  Or, should users who use EIT as their only source of 
listings data be running mfdb, anyway?

Thanks,
Mike
