So I modified its source to include my box's vendorid, then compiled it. Toggling the power of the cable box with "-w" works, but all it does is toggle.

Here is the real problem... I would suggest renting another cable box
and hiding the one for mythtv where it wont be turned off accidentally.
Put the other one at the tv set for when you really really must watch
live tv. Or even better, put both on your myth box so you can record and
watch at the same time. I doubt I could go back to a single tuner box
again, too many shows on at the same time.
