alright...cdfreaks forum
my problem wasn't the DMA issue, its a problem with some plextor's and the nVidia drivers i had running...uninstalled the nVidia drivers, burned a disc, and everythings back to normal...
so for future reference, anyone having "device/drive buffer level" issues with their plextor PX-??? drives, if you have nVidia installed, uninstall the drivers and use the defaut windows drivers.
Five--assuming yer runnin XP:
-right-click My Computer > Hardware tab > Device Manager
-expand IDE ATA/ATAPI Controllers -- look for yer IDE Channels [there's probly a Primary and a Secondary]
-double click the Primary IDE Channel > Advanced Settings tab > change Transfer Mode to "DMA if available"
--repeat for the Secondary IDE Channel [no need to mess with the Controllers tho]
