If you look closely at the media, you may detect small irregularities near the outer edge
I already noticed these, but as there are some more media I have that have the same irregulareties but still read very well, I didn't think them to be the cause.
You are experiencing typical cheap media behaviour
Yeah I know.. I just figured that after a few good stories I heard from people that bought these discs and some very good scan results on R02 I found on the board, this was a safe choice. I guess that Ritek still hasn't learned and that the quality is still batch-dependant... and that sucks
the only solution is to limit your burns to around 4000MB
Nah... I just contacted the webshop and I just hope they take them all back. I don't want half solutions...
The drive that burnt the disc is usually much more tolerant of errors then a DVD-ROM or set top player which would explain why the NEC can read it
Normally I would agree on that, but as the NEC is such a crappy reader, I never thought that this would be the case. I still doubt it, although there might be quite some truth in what you're telling me.
Another little update: I just tested these media at a 2500a and they even don't work in there. At 93% of the disc, the burner give a write error and that's it.
