Why? The channel change script detects when the channel is an on-demand
channel and simply causes an IR transmitter to send the appropriate
start codes with the channel change. Then, the on-demand starts playing
and Myth records it. From the point it's started, it's no longer
on-demand--i.e. you don't pause it or fast-forward or rewind--it just
plays. Since Myth is recording it, you can pause/rewind/etc. in Myth.
Note that there's absolutely no "remapping of remote buttons" or
"passing the IR signal from the PVR-350's IR receiver to the PVR-150's
IR blaster" or anything special except the sending of the appropriate
start codes because it's an on-demand channel.
