I don't really care if they "enhance" it. And for remastering I'd settle for cleaning it up a bit.
My only problem with the DVDs is how pixelated everything looks--especially the nacelles/engines and the credit fonts. Sometimes the credits are unreadable.
I agree. You could certainly clean up the fonts and enhance the image a little.
Indeed, you might redo some dodgy effects shots and then add in a little grain and noise to make it match the rest of the shots. You could redo all the exterior shots and just fuzz them up enough to have the viewer believe they were watching the same show.
