I recently got a nice looking copy of Shape Shifter from evilbay and it would sort of play then lock up and the audio would intermittently stop or skip or not play.  I looked closer at the disc and found what appears to be some de-lamination/ holes in the foil.  I tried my home method of disc restoring and had it professionally done as well.  The result is the same.  
So, does anyone have a copy they're willing to let go of?  I don't care if it's disc only as long as the damn thing plays.
