Detection isn't an issue.

Err, one constant stream?  You want to reencode the video so it has the same 
properties as the first one?  How would that possibly work?

Not sure what you're getting at.   The recorder/channel objects don't care 
what the stream is, only the player does.

Basically, the player object treats video stream attributes like width, 
height, etc, as constants, as there's never been a reason to allow those to 
change before.  Quite a few things would have to be done to allow those to 
change mid-playback.  Shouldn't be slightly easier to do on a channel change, 
where the player's already paused and is going to dump its buffers, but I'm 
not sure how hard it'd be to just handle it generically.
