I received an HD receiver from my CabCo (a Motorola DCX700) several weeks back and I have started to look at how to integrate it into my Myth TV setup before their analogue cable services are discontinued on January 1st 2013.

I'm running a Hauppage 250 on a single front/backend box.

The cabco told me the unit used IR and through a helpful suggestion of one of the forums users, I sourced a cheap IR Blaster. Quickly figured out after I unpacked the HD receiver that the box uses RF instead of IR

I've done a lot of googling and can't find anything that would allow my myth system to send RF signals to the HD receiver to change channels.

Any suggestions?
