Query: Sad

I finally got down to watching this set and I am so Sad. The picture quality is terrible for a DVD release! There are double edges on everything in the background and scan lines running throughout most episodes! How could they justify putting this out in this condition. I wonder if I will ever see Lost in Space in Pristine condition. Very Sad. Shame on you Fox!
