You can do this with a custom/power recording rule.  Re-recording is as 
easy as using (or inverting, or making so it doesn't care which came 
first--SDTV or HDTV recording) the example clause added for 0.24 in 
http://svn.mythtv.org/trac/changeset/25056 (note that it will work in 
0.23-fixes or earlier, too).  Just put the "rule.subtitle" stuff in the 
additional tables field and the "rule.description" stuff in the SQL 
field of the custom rule editor (and, as mentioned in the rule title, 
you'll need to disable duplicate matching).

If you want to allow recording both simultaneously, you'll have to do a 
bit more work to make sure you don't record 4 or 5 copies in SDTV 
simultaneously from different channels or whatever.  However, playing 
around with that rule should get you started down the road to finding 
the right SQL.  (And when you do, please post it here.)  Note, also, 
that there are quite a few people here and on #mythtv-users on IRC who 
know their SQL and people who know MythTV's schema well enough to help 
out--so if you have questions as you're making your SQL, please ask.  If 
you get a nice approach for doing it, I'll add it as an example clause 
to MythTV proper.

The biggest challenge is editing the rule due to the lack of a 
multi-line text widget in mythui.  Therefore, I recommend creating the 
rule (with some super simple SQL) using the frontend, then use MythWeb 
to edit the SQL.
