I'm sure that different recievers handle this differently. My sammy 360 goes into screen saver mode if left unattended for too long, and you have to change channels to take it out of screen saver mode. I usually turn the tv off anyway, since I'm listening to music.
What would be very cool, is if on the D* website they scrolled the song info for each of the channels. That way you could see the name/artist right away, no sat. bandwith is used and no one would burn in their televisions.
I honestly don't know if any of the recievers can display the info the way that you are looking for, Harrelson 69... perhaps try a sat. radio service???
