The Flesh and Blood Show 3D Blu-ray (1972) [Region A Locked] [extra feature only]

[DVD Phreak]

Anyone can comment on the "Flesh and Blood Show" 3D sequence included as a bonus feature in Kino's "Pete Walker Collection Volume 2"? The reviews here and DVDBeaver mention nothing about it. I watched it on my Nvidia 3D Vision Windows PC with PowerDVD, and noticed some of the 3D effects were barely there, even though the clip only runs about 5 minutes. Sorry for sounding like a pervert, but there is a fairly close, frontal view of the a well-endowed, topless woman (actress Jane Cardew), and her breasts don't "pop" at all. One of the few notable 3D effects is the villain pointing a knife towards the camera. I guess I would to know if this lackluster 3D presentation is due to bad film elements, bad film-making, and/or some other reasons, and whether a better restoration would be possible. I'm aware that sometimes even in nice restorations of 3D films, there are "errors" in the 3D effects such as temporarily loss of separation and/or reversal of left-right shots, etc.
