I watch a couple of sporting events a week, almost exclusively via DVR. Why? I'm busy with a toddler, job, etc. I'm busy enough that I probably haven't seen the score yet, bit, even when I have, I often want to understand how (or watch awesome plays).
So how do you monetize me? How about not stopping so regularly for such long ad breaks? Right now, my ad viewership in these recorded games is zero. I blow right by ads via a DVR. But, if it was a 30 second ad here or there, I'd just sit back and tolerate it.
