I would rather count on the media player (Blu-ray player or whatever) or TV to do it than in the source. Think of it this way: in NTSC, DVDs were either had hard 3:2 pull down for 24Hz to the 29.97Hz to show on the interlaced CRTs of the time. But now that we have TVs that can show 24Hz, if you play those DVDs they still have the interpolated frame artifacts. While if you left it up to software pulldown in the DVD player (which they basically all had, since I believe it was part of the standard), they can now be shown at the proper frame rate without interpolation.
Most theatrical DVDs released after the early 2000s were 24Hz, as far as I know and depended on the DVD player to convert to NTSC. So now in modern players, they're outputted at 24Hz for 120Hz and 240Hz TVs.
The only downside is if you get crappy TVs and/or Bluray players that do horrible pulldown, I guess. But I've gotten hardpulled down DVDs that look horrible as well (I'm looking at you, BBC).
