I, too, have the NEC ND-2500A. I have only had it for one day, but I plugged the sucker in and ripped a data CD-R in 2:30. Gotta love plug-n-play!
I cruised over to Best Buy, picked up 2-50 packs of the Fuji 8x DVD-R's for $19.99 each. I came home and began clearing off the hard drive faster than expected. The NEC records to the 8x DVD-R's at 12x w/o any repercussions. Very, very pleased with it so far. I can burn 4.7 GB of data in the same amount of time that my old Plextor would make an audio CD. !!!
So late last night and early this a.m. I followed the Wavelab DVD-A tutorial for a show I did at 24/48 (in the Archival section) I began renderding it as I was leaving for work. I sit hear dying slowly wondering if A) It will record OK without gaps, and B) Will my older Pioneer DV-525 player play the DVD-A's ok.
