Sorry, my use of "through" was with respect to the video signal, not
the command signal -- i.e., the video comes into a video capture
device "through" a cable box, rather than directly from a coax feed.

You send the same thing to both an IR transmitter script and a
firewire channel change script: freqid. The actual implementation
details (use irsend, use 6200ch, pad with zeros, send an enter key at
the end, whatever) are handled within the channel change scripts
themselves.
