That's the word, with a small but vocal group of subscribers claiming their discs are repeatedly arriving with small cracks on their outer edges. It's unclear what might be to blame, even with the extra coating to prevent scratches on Blu-ray, they could still be susceptible to automated mail processing machines, manufacturing defects or perhaps a spontaneous game of mail Frisbee. The Mars Box blog experienced this issue back in '07 with the disc pictured above, but in the last few months reports seem to be picking up again. It's really too bad those extra costs can't buy tougher packaging like the cardboard slips GameFly uses, but Netflix told Wired the problem is "infinitesimally small" and changing shipping wouldn't be cost effective. We know plenty of you rent your discs, let us know, have you been afflicted?
