TV modulators are available in many electronic stores for $25-$30. The 
are generally intended to be used to connect older video cameras etc to 
coax only TV's.

I'm using one right now to pass S-video output from the mythbox to a 
circa 1982 Sony 27 inch trinitron TV... Just set the TV to channel 3 or 
4 and feed the input in.

You may also want to grab a video switch which has 2 separate coax 
inputs and one output. This would allow you to have you VCR as one input 
to the TV and your mythbox + modulator on the other.
