Hoping that some of you radioheads can say what the deal is with the commercials mvp/scr (does anyone have the minutes per hr numbers?)...ie why are there so many more on scr?
Is this just the espn name allowing mvp to charge more per spot and therefore go lighter, or is scr being greeedy?

I ask because it's a major reason for my tuning to mvp, even when the content edge for a given program might go to scr...
