Another option is a program I wrote that checks for power status on the 
STB and then you can turn it on or off. I expect this will work on any 
STB as I use the original power codes defined in the late 90's. I also 
have a script that does the power status check before turning on the STB 
that way you save an additional second as the power on requires a 1 
second guard time.

Check out: http://code.google.com/p/sa3250cmd/

don't be spooked by the name sa3250. When I first wrote it, it was for 
sa3250 and sa4250 boxes but it should be generic and has also been 
verified on the Motorola DCT series. Let me know if it works or not on 
yours and I will add it to the compatibility list.

Also note majoridiot is using the same power codes but I don't remember 
what logic he checks before doing this so it may/may not work with the QIP.
