Query: Worst mastering I've ever seen

I concur with all of the reviews below. There are major flaws with the mastering of this DVD. Any significant motion on the screen results in lines and bluriness on the moving object. This DVD is nearly unwatchable. I can't believe it was released in this state, and it should be recalled. I recommend staying away from this issue at all costs until this is fixed.
