I've never heard PAL pulldown called "telecine". In any case, pullup
is designed to handle ANY form of pulldown, whether it's 2:2 PAL, 2:3
NTSC, 2:2:2:2:2:2:2:2:2:2:2:3 PAL, or whatever. Of course for pure 2:2
content, no pulldown reversal is required unless the phase is
backwards, since the fields already line up to give you progressive
frames with no rearrangement.

Regarding the others: detc will NOT work with PAL pulldown unless you
get very lucky. ivtc might work (as long as you don't enable forced
dropping with ivtc=1) with either type of PAL pulldown.
