I just installed a DVR-110D in my machine. Machine’s a 2.5 gig Celeron. I have an NEC 3520 as master which runs UDMA mode 2, The Pioneer is set as slave and it runs UDMA mode 4. The NEC burns fine at any speed. The Pioneer, at anything above 8X, starts draining and filling the device buffer from 0 % to 95 % and back to 0 % as soon as it passes the 8X mark. This happens with CMC 12x and Taiyo Yuden 12x dvd-r discs. I don’t have any 12x dvd+r’s If I record at 8x, as soon as it hits the 8x mark the buffer keeps dropping an the speed drops to 7.5 then back to 8x. It constantly does this AT 8X. IS THIS FREAKIN DRIVE JUNK ??? I have a brand new 80 wire IDE cable on the drives, The hard drive is freshly defraged and the NEC is working fine.
