The fullscreen dark_Jedi transfer shots didn't IVTC properly - it seems that the film was slightly sped up in the conversion to cheap laserdisc, and it's not a normal pulldown at all, it skips fields all the time. I am hoping that the fullscreen Jedi IVTCs properly, as that was a better laserdisc transfer.
The fact that I can't use this fullscreen version of Empire is not a huge loss, as the fullscreen transfer for Empire was kind of poor.
