I have a problem with my PX-708A burning slow. It is able to burn good dvd's and cd's, but it usually takes me over an hour to burn a TDK 4X DVD+R which is compatible with the drive according to Plextor's homepage. When I determine the speed with the Nero Burning ROM that came with the drive, it says that it could only burn at 2X instead of 8X due to the speed from the source is too slow.
I've checked the forum for similar problems, read the stickies, upgraded to firmware 1.06, checked the Device manager that the DMA enabled, checked the BIOS settings and where the UDMA settings are on Auto and put the drive in secondary master. It's still the same...
My machine is a Shuttle SN41G2, running on Windows XP Service Pack 1.
Thanks for any help.
