I have the same problem too on Windows 2003 server.
I need to find a way to prevent this from happening.

If You uninstall the controller it will be back to DMA.
See IDE ATA/ATAPI controllers
Primary or Secondary IDE Channel
You may need to restart the computer twice if the System hard disk and the
DVD are connected to the same controller.
If it doesn't ask You to restart, click the Scan for hardware changes button
and You're done.

I am glad to help You!
And if someone tell us how can we disable the automatic change to PIO mode,
it will be just perfect!
All I know that if something goes wrong durring a read operation You should
eject the disk, before It goes in PIO mode. And don't keep CDs in the drive,
when not used.

Good Luck!
