[mythtv] suggestion for rewinding in mythtv

I've thought about this a few times, and rewinding over channel changes does
seem a bit strange, but I think it could work.

I guess you've got to then decide which channel the 'live' tv stream should still be 
on, and what then happens if you try and change channels again whilst in a previously 
rewound stream (that already contains a channel change).
Does it go to the end of the current 'live recording' and change channels there,
or should it cut-out what's currently in between what's currently being watched, and 
real-time.

lots of confusing and non-intuitive decisions.
