The total amount of minutes accumulated when starting a show on a DVR after it has already started to air live. Used generally to fast forward all the horrible commercials and horrible ads no one wants to see.

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 1: Hey, can we start the Cavs basketball game already?!?!

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!
