So your callsigns changed from, i.e. "Channel 36" to "USA". You may
want to consider changing your rules to "Record at any time on any
channel" rules so this won't be an issue again. Limiting a rule to work
on only one channel requires you to verify that your callsigns /never/
change. Also, by allowing recordings on other channels, Myth may have
more options, may find showings that you may otherwise miss, ...
