The problem with many of the media with the VDSPMSAB 01 media is that this MID is generic. It's the Interaxia AG staper used by Sky Media Swiss (poor quality), 3A Media Austria (good quality). Like every manufacturer 3A Media has probably got A and B-grade media. Their current problem is compatibility by the drive manufacturers, due to the fact that they are a rather small manufacturer (500.000 to 1.000.000 discs a month), which is peanuts compared to the Asian production numbers. Therefore drive manufacturers don't work very hard to support discs of small manufacturers (most Europe based producers suffer seriously from this problem). Some drive manufacturers are more willing to cooperate (BTC, BenQ, Philips, Plextor), but others (NEC, LiteOn, Pioneer, LG) are very slow in implementing the MIDs and a correct writing strategy. But with my custom patches, great results have been achieved already on LiteOn and NEC drives so far (proven by CATS, BenQ Pi/Po/Jitter and LiteOn Kprobe). So it's more LiteOn that doesn't support these media properly then the media itself being crappy. I've been working with 3A Media for the past 2 years almost and must say they have come a long way, getting a fully working production line with great quality discs from scratch, most of it by trial and error, since Asian companies are not willing at all to share any kind of knowledge.
