I had Philips041 DVD+RW 4x discs brought under the brand name of HP (Hewlett-Packard). They were burnt on a BenQ and a NU-Tech with brilliant results 2 months ago. They had errors PI<20 and PIF<2 which is great for RW in my opinion. But two months later, the discs started losing data - I lost 1.2GB over 5 discs! I decided to scan the discs today - and guess what? The PI/PIF is exactly the same, but the disc has unreadable files? I know this happens, but this is an EXTREME DIFFERENCE between the PI/PIF and readability! The graph is nowhere near 280! I heard these discs are CMC Manufactured - can anyone vouch for this?
