I just bought a Mad Dog 16x, which I immediately flashed from 2F.6 to Liggy's NEC 2.18. Grabbed the newest version of Nero (6.6) and was surprised to find it took 14:10 for my first burn at 8x on a Maxell Made In Japan DVD+R disc, media code Maxell 002. I've burned the same media at the same speed in about 8 mins on a Sony DRU-540 (Optorite drive), so I doubt that's the problem.
I'm running the burner on primary master, UDMA Mode 2.
What could be the problem?
