You might also want to change the group name for the remote recording (to
maybe , 'Remote')so that they are not mixed with the rest of the local
recordings(Default)  and you wont select with mythfrontend accidentally on a
nonlocal file.  On the master backend, create a batch script and run with
cron  that compares local and remote filesizes  for each individual mpeg
files under the 'Remote' group and then have it change the group name entry
on the recorded table to Default once local and remote file sizes are
equal.  This way if the recording shows up in Default, then you know you
have the complete file locally.

Of course, I could be wrong at so many levels. But this is indeed
interesting.  I might try it myself.
