I recently bought a spindle of Philips 16x DVD+R CMC MAG M01 (The one from boxing day at Futureshop). These discs had decent scans from another user, so I decided to keep mine.

I just tried burning a DVD movie ISO at 8x, and the Nero CD/DVD scan gave me a PI Failure of 13308. The quality score is 90. The Nero verification was fine, and the scandisk gave me 100% green I've tried looking through it on the DVD player, and it seems fine. Is the high PIF a big problem, and would that warrant a return?
