hopefully I can get some help here on this matter.
When comparing a dv pal movie (yes, PhotJPEG has the same results) which is played out via jit.gl.videoplane and the same movie played out via jit.qt.movie?s "@window foo", the opengl variant looks much more jerky.
It gets most obvious with movements in the scenes.So for example moving clouds on a sky are no more acceptable as a background projection.
I am attaching a comparison patch, so if anyone has an idea what is wrong I would be glad to hear.
P.S.: Using H264 the error gets more pronounced.
