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? - Grant
