Not long ago I put in my old CD-RW as the slave drive on the cable where my nd-3500ag is the master. Since then, it seems that my dvd-rw is burning slower than it used to. I just burnt a DVD set at 8x - it stuck around 4.1x until about 20% then jumped to 6.1x until about 50% then rose to 8.2x and not long after dropped back to 4.1x and occasionally hovered below that. I'm using the 2.18 dangerous brothers firmware and burning on Ritek 8x dvd-r (i think ritek g05 discs). I've burnt discs with dvd decrypter and alcohol 120% and had the same speed results. Any ideas as to why it's doing this is appreciated. I'm pretty sure the dvd-rw jumper is set to master although i'm not sure. the cd-rw is slaved. Thanks.
