But then I would loose all recordings.

There's no way to just downgrade?

Well, there are two more options:
 1.  Go through the last year and a half worth of commit logs to SVN trunk and look for anything that changes the schema. Check to make sure that schema change isn't also in 0.20.2. Take the list of all these schema changes and write a script that reverses them
 2. Make a backup copy of your current DB. Restore from your 0.20 backup and immediately upgrade to what your current version from SVN is. Compare the two databases (your current DB and the newly upgraded one) to see what's different and write a script of some sort to put that new information that's in your current DB in the 0.20.2 format.

The real life practical answer is that there is no way to downgrade. There is only restore from backup.

0.21 fixes doesn't work for IPTV or the mpeg2 stream I'm trying to watch.

Or, as mentioned here, deal with the shortcomings of the current development version. It sounds like you have to pick now which of the two bad options is better for you.

Or could he possibly use mythrename to give the new recordings meaningful names, restore the old DB/program files, and run myth.rebuilddatabase.pl to import the new recordings?
