There is a whole bunch of helpful stuff at http://www.tomshardware.com/forum/196090-32-lite-dvdrw-160p6s-burning-problems
Seems that the drive may overheat, and will need replacement if in warranty. Some advice given: get another type drive. Also, check the device manager and make sure it's running in DMA mode and not PIO mode.
If you have an nForceX mobo and using the SW IDE driver, reinstall with the normal IDE driver and try again.
In device manager, check under IDE ATA/ATAPI controllers
. Right-click and select properties on the IDE Channel
your DVD recorder is attached to. Transfer mode should be set to "DMA
if available". Current transfer mode should be "Ultra DMA Mode 4". If it says Mode 2: Your drive may be experiencing problems which are causing windows to drop its speed. There is a support article
with a fix. To surmize:
After the Windows IDE/ATAPI Port driver (Atapi.sys)
receives a cumulative total of six time-out or cyclical redundancy
check (CRC) errors, the driver reduces the communications speed (the
transfer mode) from the highest Direct Memory Access (DMA) mode to
lower DMA modes in steps. If the driver continues to receive time-out
or CRC errors, the driver eventually reduces the transfer mode to the
slowest mode (PIO mode).
If you have dropped from DMA mode 4 to DMA mode 2, and you have a spare
ribbon cable, you may want to try swapping it out. Also, if there is
another device on the same channel as the DVD drive, try disconnecting
