    All progressive scan DVD players should do 3-2 pulldown (or 2-3 pulldown) correctly if the DVD is correctly pressed.
    Film source DVD has two interlaced video fields for each film frame (1/24'th second) stored on the disk. The player creates the 3-2 pulldown by re-using some of the material, so there are 60 fields per second (interlaced) or 60 frames per second (progressive).
    The problem arises if the DVD is not correctly pressed or if the source material was not a 24 frame per second film, then some progressive players give a better picture than others. I don't know which models do it best, but those with Silicon Image chipsets are extremely good and do everything.
    If the DVD player has a menu to select 3-2 pulldown vs. video mode or something like that, chances are it is not the best. The need for manual selection usually means that the progressive scan circuits are less sophisticated.
