He waves his wand and ...ta-da... the blended fields re-appear...
Thanks for the hint.
As you SHOULD have read in another post of mine int that "other place" telecide is not an option for these clips, it always gets the field order horribly wrong.
As for star trek, I am actually testing this with something different for the momment (the making of animatrix). The point is though that the problems with both this one and TNG DVDs are not so much in the video part as in the film part! Since there is so much video, the "brilliant" guys at paramount used the famous blending technique of reducing the framerate throughout the movie/episode, WITHOUT first aplying some IVTC on the film parts!
The results as you can imagine or probably see for yourself are horrible, where they could have been almost perfect.
The same goes for most making-of featurettes, like the one I am using.
