NOTE: The configuration shown in Figure 6 can make it very difficult to
write from the DVD or CD drive to the PX-712A at maximum rated speed
using “on-the-fly” copying.
System configuration and performance will make a big difference.
Depending on how fast the DVD or CD-ROM drive can stream data to
the PX-712A, it may not be fast enough to keep the buffer full. In this
case, the buffer may become empty and a buffer underrun error may
occur. However, because it is equipped with Buffer Underrun Proof
Technology, your PX-712A can still make successful copies if you use
software that supports this feature. (All software shipped with PX-712A
drive retail kits supports Buffer Underrun Proof Technology.)
If you still have problems writing with this configuration, use the image
writing method (that is, write an image to your hard drive, then write that
image onto the DVD±R/RW or CD-R/RW media), or record at a lower
speed for best results. We also recommend that DMA be enabled on
your computer, if your system supports it.
