I watched the XFinity race and with the help of DVR, I enjoyed it.
I'm to the point now where I can't watch any race "live" because of all the commercials and all the caution laps/breaks. I set it up to record, and then when it should be about 3/4's over, I'll start watching it from the beginning with one finger on the fast forward button, zipping through all pre-race babble, all commercials/other, and it usually works out that I'm just about at the very end of the race as it is really happening live.
Makes all NASCAR series more watchable. From what you guys have said before, I'm not the only guy using their DVR to watch the races these days.
