I tried it with the spaceballs DVD some weeks ago and it worked fine. The Spaceballs DVD is a letterboxed transfer from a laserdisc-master too.
The picture of the "source" of this Spaceballs DVD is very soften and so was the result: The picture was very soften. Who knows yet, how the picture of the OOT-DVD's will be in fact, and:
now here is my question:
Is it possible to sharpen the picture of the OOT-DVD a little bit with the DVDRebuilder? I don't know, if there is anybody, who uses this program and could give tips. As I can see they can use filters with the DVDRebuilder, but I don't know how to get the best picture-result.
Maybe there would be one who could post a "how to" guide, if he uses other tools.
