This is what I ended up doing before moving all of my recording to a
CableCard tuner.

But just as a forewarning, consider the case when you are trying to
transmit on both transmitters at the same time.  (Say two recordings
fire up at once.)  You need to either make sure the irsend
SET_TRANSMITTERS command come before each key sent, or use some sort
of touchfile locking to only allow one script at a time.

Good luck,
