hi i have a dual 859 dvd divx player, i have noticed on some files i play on it in divx or xvid the playback is jerky, particularly when the camera in the movie is panning. i wondered if this could be due to the fact that the files frame rate is 23.976 fps as i was under the impression that pal video files should be 25fps? could it be the frame rate that is causing the jerkiness? if so how could i fix that? would i be able to rencode it to 25fps or something?
