Well Ive had a second opinion that it plays fine in other players like an Oppo.
I wont give up on this though and I will be like a dog with a bone investigating this further.
Somethings up and Im not imagining that my players cant handle that disc without vibrating quite badly. I cant see that the spindles in my drives are that much worse for the job in hand than more expensive players.
I would have thought most video disc drives are based on a lot of plastic now.
I will have to build up a spindle and investigate this to the nearest micron
