Now I'm really puzzled about what you're hearing/seeing with Friends. You can't just speed up a videotape like you would an audio tape -- put simply, all hell breaks loose. What you can do is use editing software that pulls out every "xth" frame -- but to make up a minute in 22 minutes of show, you'd only need to zap .... *calculator keys tapping* ... about 82 frames per minute or a mere 2.7 frames per second out of 30. Assuming some decently programmed software (like what I have on my computer that costs less than $100 ...) that should not make much perceptible difference at all. Also, when network shows are shot, there are cut points built in to allow them to be shortened for syndication with no speed alteration necessary.
So, what I'm saying is, based on what you heard, they're putting in at least two more minutes of commercials and maybe more.
I'm not gonna be hunting down a daytime showing of Friends, so .... I'll probably just stay mystified unless
Kalel chimes in with some more current tech than I know about.
