It could very well be that your IDE channel has reverted to PIO mode, should be (U)DMA. IDE ATA/ATAPI Controllers --> Secondary IDE Channel (or
possibly primary) and double click it. Check the advanced settings tab. If the device is in PIO mode uninstall it.
Reboot the machine and let Windows reinstall the IDE channel and the DVD drive, then check it again via Device manager.
If you are in some form of DMA mode, preferably Ultra DMA Mode 2, then you should be good to go.
If that doesn't take care of it, you may need to go into the BIOS and turn (U)DMA on.
Let us know how you make out.
