codes, doing a third was no extra work.) Then, I set the channel change
script for my inputs to use "change_channel dish" and "change_channel
dish9" where change_channel is a script that accepts a LIRC remote name
and a channel number and sends the appropriate signal.

receivers right next to each other and control them with a single
transmitter. To do this, you need the improved transmitter--the LIRC
simple transmitter doesn't have the range or breadth of signal to
control more than one device.

It definitely costs more than the simple IR transmitter, but it's still
not too expensive (maybe $10-$15 IIRC). However, my MB only has one
serial port (and doesn't have extra headers or anything), so I had to
control both with a single transmitter.

RAW. I've never been able to get the non-RAW codes to work, but the RAW
ones work like a charm.
