@Dulus: thanks! You are right, there were a missing FIELD that messed up the cadence, I’m working on the first part, the second should be similar so I think no problems with it. If you noted other problems like that, please report them here.
@SmegPod: thanks, I like it too, more than non-grained version. “Untouched upscale”, what do you mean? Untouched original video, just upscaled? Warning, it will be quite ugly, and I don’t see the point - you can always get almost the same result watching the laserdisc through a video processor (or even a simple DVD recorder, that will be used in pass-through mode to decomb and deinterlace).
