Hi Mike,

Many thanks for your reply.  This is actually what you suggested to me
a few weeks ago, but I couldn't work out how to best run that script.
Are you suggesting the modded myth_archive is run as a user job after
a recording?  The problem I see here is that we could still end up
with a disk that is getting full and then myth could still decide to
use it for recordings, to a point where the disk runs out of space.

I was looking at creating a cron job that will run every 30mins or so,
that will run a script to simply move files from a somewhat full disk
to one that has space or has plenty of deleted recordings.  I will use
the myth python bindings to prevent me moving files that are currently
being recorded to.  The only problem I see is that someone may start
watching the same recording I am moving during the time it takes to
actually do a filesystem move.

Anyways, fun times ahead.  Let me know if you foresee any problems.

Regards,
Whytey
