For an NBA game, you typically need at least 45 minutes of recorded show before you can hit "play" (depending on the speed you fast forward) to be able to skip all the commercials and halftime.
Friend 2: No! We only have 27 minutes of fast forward time, and I don't feel like seeing that annoying McDonald's singing fillet-o-fish commercial again!
Buddy 1: While we were gone, the football game has been recording for almost 2 hours!
Buddy 2: Awesome! We got some MAD fast forward time yo!
