Query: Horrible Video Quality

Remember when you used to have a VCR and would sometimes try to watch a video tape that had a picture that kept bouncing up and down until you adjusted the tracking control? Well, that's what this DVD is like. Which is simply PATHETIC.I'm not a videophile by any means, but even so, watching this DVD was a horrendous experience. I turned it off after fifteen or twenty minutes as my eyes and equilibrium could take no more.The narration seemed to be fairly informative, but who can listen when the picture is this bad? What a waste.
