Yes, hmm... Maybe I should make it an option to vf_pullup, whether to
use DR or not. It matters A LOT for realtime playback, but for
encoding, it's a tiny percentage of the whole process.

Actually softpulldown doesn't pass along the flags; it converts soft
into hard telecine. :) But you're right, that is a good choice!

ohhhh...that bug. why are you putting mpeg2 into avi and then trying
to encode from it afterwards? there's probably a better way to be
doing what you want. however, we should find a way to fix this too...
