OK.  This sounds like a problem with your external channel change 
(script/transmitter or serial link/STB).  If Myth said it's going to 
record on channel 4, but recorded 3, it wasn't Myth's doing.

OK.  Then this means that--regardless of recording type--when Myth 
identifies that two channels are the same, it will *always* use the 
preferred encoder.  The more I think about it, the more that seems the 
sensible way to program it.

OK, if they really are different sources, then leave it that way.  (I 
thought you only created a different source to allow yourself to specify 
which encoder to use.)

The only time encoder 2 will be used is when encoder 1 is already in 
use.  By default, encoder 1 is used (basically, encoders are chosen by 
priority, but in the event of a tie, the lowest-numbered encoder is used).

You can set encoder priorities using mythtv-setup and you can tell it to 
use the least-preferred encoder for LiveTV (something about minimize 
encoder conflicts with LiveTV), but otherwise, Myth will choose the 
lowest-numbered available encoder for all recordings.
