I have just noticed, after about 2 months of owning this set that the die hard 2 second disk, i.e the extras has imperfections on the disk. I was having problems playing the making of it and some trailers and other bits. I looked at the disk very carefully against the light and it's very clear to see what can be described as bubbles on the cd all over the place. The bubbles look as they they are under the final coat surface. Purchased from a guy on Ebay who sold it as brand new and wrapped, which it was. It was delivered direct from CD-WOW !!!!! I am going to write to CD-WOW to see what I can do.
