PAL speedup question

[wallywalters]

I have an ISO file, apparently from a retail DVD, containing some "Married... with Children" episodes at a 25 fps frame rate. When I ripped them to MPEG2 I expected to find them suffering but PAL speedup, but the running times were correct, the actors' voices were all at the correct pitch, and it didn't seem sped up in any other way. Ordinarily when I come across a 25 fps video that originated on American TV I'll make a 23.97 fps viewing copy that conforms to NTSC specs, because the helium voice effect is too annoying otherwise.

My question is, shouldn't there be PAL speedup on a 29.97 fps NTSC video converted to 25 fps PAL? Why isn't it present here?

They probably took analog NTSC video tapes and passed them through an analog NTSC->PAL converter that blends fields. So there is no change of running time. It's quite rare that they would go back to the original film (if it was shot on film) for a TV show.

FWIW, Married With Children definitely originated on tape.
