Thanks for that.

Not sure the last bit is exactly right though. I got errors until I
changed it from
   prog = Program.fromRecorded(rec)
   prog = MythTV.Program.fromRecorded(rec)

Hope that change makes sense.

However I still get a problem with the backendCommand call though:

Traceback (most recent call last):
  File "./myth_refresh_rec.py", line 16, in <module>
TypeError: join() takes exactly one argument (3 given)

I'm no python expert at all, having never used it, so hopefully a
quick pointer in the right direction would be much appreciated,

I'm using recent 0.24-fixes from atrpms on Fedora 14, if it makes
any difference:
