That solution works fine for LiveTV, but not so good if the system is attempting
to record something...
Remember, LiveTV is just a specialized kind of recording anyway. Would you
rather your scheduled recording be aborted and rescheduled, or would you rather
have a recording of something random from an arbitrarily selected channel?
I think in these circumstances, an abort back to the menu should be the only
response available. For LiveTV, a means for the user to pre-select the channel
might be the way to then deal with this issue.
