Default RF modulator needs video to work?

I was hoping the screen would be black when I was only listening to
sound. Of course I could turn the brightness down. But then I'd have
to turn it back up again later.

I'd also have to turn off the video when I was done too, not to waste
electricity, and becaues I'm going to want to go back to the antenna
signal.

I'm hoping to make this all work as smoothly and conveniently as
possible.

Hmm. What would be convenient is if I could just split the R and L
audio into R and L1 and L2, and run L2 into the video input. Do you
think the RF-modulator can tell video input from any other input
signal? The tv screen would stay black, I'm sure.
