I just had a new experience with a Netflix rental (Band of Brothers, disc 3).\nThe playback was stuttering slightly, so I took the disk out and saw some light\nfingerprints. I used the edge of my clean t-shirt, and gently wiped it off,\ncenter to edge. I then noticed that part of the silver surface had turned a\npale gold color. I wiped some more, and realized that everywhere that I was\ntouching was turning to gold. So I wiped the entire surface down, and now the\ndisk is completely light gold. But unfortunately, the flat reflective surface\nis also noticeably warped. Now the disk is unplayable.\n\nI'm assuming this is a manufacturing error, and I've never seen this on any\nother disk. Was it bad glue? Advanced rot?
