Query: Full disclosure recommended:

This DVD is substandard for its' cost. It seems as though the DVD was recorded from a copy of the original version taken by the viewer as they watched it on a screen. The picture is difficult to watch, making you dizzy at times, many distortion lines running through the production and the picture is often off the center of the screen. I do not recommend the purchase.
