have tried to set my dvd player to dma mode but it is

proventing my to set my settings to dma.

Windows sometimes automatically degrade CD/DVD drive mode from DMA to
PIO mode ones it encounters errors during read/write operation. This
can happend due to a poor CD/DVD media. Once degraded it is not
possible to turn it back just via the Check Box on Device Setings
panel. You have to uninstall the CD/DVD device,reboot the PC and
install the CD/DVD drive again (it will be installed automatically).
Now try to change the CD/DVD drive mode via Device Panel (if the DMA
mode is not already set ).
If you still can't set the DMA mode, your CD/DVD drive doesn't support
DMA, or the drive is faulty.

Good Luck
