Have you guys considered something like this, which comes from the xine list:

>> There are two steps to it:
>> 1) The DVD plays at 30fps in the US.
>> If it is a "movie", the DVD tags some fields as "repeat first field" so
>> this causes a 24fps film it to play nicely on a 30fps display.
>> A computer monitor is not 24fps or 30fps. 30fps, so rather than try
>> displaying at 30fps, one tries to display at 24fps.
>> xine correctly does this first step.
>> 2) Once one moves to 24fps, the PTS values on the DVD mpeg stream are
>> correct for 30fps, so would display showing a small amount of judder.

It doesn't sound perfect, but it should be an improvement, right?
