Burning with Plextor-716A?

I just purchased a P-716A and I was wondering if anyone could help me get it burning at peak performance. I keep getting buffer under-runs. Is there a good DVD-ROM drive that can optimize my performance? My DVD-ROM is probably too slow to keep up with the Plextor.

First, please ensure that you have DMA Mode set up properly.

Secondly, if your DVD-ROM is on the same IDE channel, then you will probably have problems doing an on-the-fly copy. (Personally, I recommend that on-the-fly should always be avoided due to it being less reliable than burning from the HD.)
