I got off work after it was over, headed home, and activated content skip on the ReplayTV. Enjoyed some of the commercials, skipped several CBS ones.
I also didn't bother to disable content skip around halftime, so my unit went right over the MTV crap.
Whatever engineer put in that easter egg at ReplayTV, thank you. It came in handy. For those with a ReplayTV 4500 or 5000 (and possibly the 5500), do the following:
1. Start the desired recording.
2. Hit the Play button to enter slo-mo mode
3. Hit fast forward to go to 3x slomo mode
4. Hit Commercial advance off, and back on. Unit should say "Content Skip is now ON"
