I /highly/ recommend you never rename MythTV recording files.  Instead, 
use "mythrename.pl --link" to create "pretty" symlinks to the recording 
files (or recording links).

Put the links in a separate directory so you don't have all the other 
"junk" in there (i.e. PNG thumbnail images, ugly-named recordings, 
etc.).  Also, "mythrename --link" will delete /all/ symlinks under the 
provided link directory (so it would delete the ugly-Myth-named links as 
well as the pretty mythrename links, leaving orphaned recordings).

And, that's what deletes the old symlinks--mythrename.pl, not Myth.  So, 
for example, I run mythrename.pl --link on a cron job at 1 and 31 past 
the hour (nearly all shows I record start on the half hour).  Sure, I 
may have a recording or two for which I don't have a link or for which I 
have a link right after I delete the recording--for up to half an 
hour--but if I really need to, I can always run "mythrename.pl --link" 
myself.

In fact, though, I never run mythrename.pl directly.  I have a little 
"wrapper" script that creates various "views" using different formats 
for the names (attached).  That means that each view--when sorted 
alphabetically (or ASCII-betically, as the case may be)--gives me 
differently-sorted recordings lists.  The list sorted by original 
airdate lets me know what order to watch the episodes.  The list sorted 
by recording starttime lets me easily find the newest recordings. ...

Have you looked at myth_archive_job.pl (which has nothing to do with 
MythArchive, BTW)?
