For those who record everything, and never have time to view it all:
Change the first Fast Forward speed so it plays WITH sound, at normal pitch, just faster.. (This technique has been available on some audio recorders for many years)
Add a menu so this feature can be enabled or disabled, and the speed customized for the viewer's preference. This way, in addition to skipping commercials, you could see an hour-long show in, perhaps 30 minutes.
(I don't have this problem, since I record in "first run only" mode, don't record suggestions, and have never filled up my 80-hour unit..)
