It gets more complicated now though as lots of TVs are capable of 24
frame progressive playback, thus avoiding the 3:2 pulldown described.
You can author a 24 frame disc, for instance, and compatible
televisions will deal with it appropriately. A digital file can also
be played back at any frame rate on your monitor, through a projector,
etc. Unless you're preparing to output for broadcast TV, these
standards matter less now.
