my DVD player converts any non progressive DVD video and outputs a progressive video. !
All PC DVD playback is displayed on a compulsary Progressive Monitor (99.9% of PC monitors are progressive). So any signal coming from timbaktu or whatever neccessarily has to be converted to Progressive. How refined this conversion is, it's another thing.
Are you viewing the original 24 film frames at 720x480 resolution 60 times per second or a 720x480 picture made from 720x240 resolution, displayed 60 times per sec?? Also note that 720x240 res of (this) DVD fields itself has already been derived by mixing up (field averaged) various PAL fields, left to be averaged out by our eyes. You can never obtain the original film frames from a field averaged DVD, no matter how expensive de-interlacer you use.
Had they kept each PAL field distinct, repeating every 5th field into 6th, then yes original film frames can be recreated (expensive de-interlacers).
On the other hand if it was a PAL DVD from a PAL telecine, original film frames are available by default.
Also, if it was a NTSC DVD from a NTSC telecine, whether it has Progressive flags or a repeated every 4th field, any cheap de-interlacer can recreate the original film frames.
