For hdhr anyway I think I could write a script that could detect
changes.  I'll probably work on that a bit but since the channels
change so infrequently it'll be a little hard to test.

In any case Myth should mark recordings like this as "aborted" or
"failed" or somehow give an indication that something bad happened.
As far as I know I had no idea that something was wrong until I tried
to play the recordings.  I can probably look into that change as well.
