After watching a few of the extras discs I put in the Matrix Revisited. I was unable to navigate the menu. I tried it in the upstairs player and the pc and it happened everytime. I examined the disc and noticed a kind of smearing under the surface. There was also a dimple too. I've sent the set back and ordered the R1 set instead (which I would have ordered 1st if I'd known R2 was still cut). Just thought I'd let you guys know just in case it's not a one off and you may of not viewed this disc for a while.
