You can apply "hard" telecine at encoding time with mencoder, but this
will greatly hurt the quality. What you want to do is use the
field-repeat flags (like most commercial movie dvds do) to "soft"
telecine the movie, so that only 24 pictures per second are stored,
and the player shows each for the correct duration to give 30 "frames"
per second.

Unfortunately, as far as I know mencoder can't do soft telecine. If
you wait for mencoder-g2 it will work, but it won't exist for at least
a month and might take much longer to become really usable. I would
recommend just using a different program for this purpose, for the
time being. :(
