The fix actually exists in 0.24-fixes.  You could choose to upgrade to 
that, though there's probably not a lot of reason to use 0.24-fixes over 
0.25-fixes--especially if anyone uses Live TV, you'll want 0.25-fixes.  
If you're upgrading, anyway, might as well go to current stable version.

Yes you could fill up some space to keep in the safe ranges.  That would 
put you basically where you were before you lost the recordings.

You could upgrade from 0.21 to 0.24-fixes, then upgrade from 0.24-fixes 
to 0.25-fixes.

Basically, 0.25-fixes requires a database version from 0.22 or 
higher--it can't upgrade any older database versions.  The main reason 
I'm recommending upgrading to 0.24-fixes (rather than an earlier 
version) is because it has some fixes for some random issues that can 
occur during database upgrade--especially with newer Qt and/or newer 
MySQL versions.
