Thanks. Well, I hope MS is seeing this as an improvement area...

It is just a counter. When xx number of read failures are detected, you
will
drop down one DMA mode. More errors, drop down to PIO mode. It then stays
there until you do as I instructed.

Thanks Richard. This fixed the problem.

Do you know if this read errors can accumulate over time, or is there
some
averaging going on?

Using device manager, uninstall the IDE channel where the DVD player is
installed. X out of device manager. Reboot. The IDE channel will be
redetected and you should be back to normal.

When a CD/DVD drops down to PIO mode, it is usually due to a bad disk.
If
there are too many read errors, the device lowers it's speed
accordingly,
trying to get valid reads. The only way to fix this is by doing the
above.

It works!

Find which disk caused the problem and toss it out.

For the longest time I resisted to install XP ServicePack 2 since
everything
worked fine. I decided yesterday that it might be time to do it
anyhow.
I went much smoother than expected.

But XPSvcPack2 created an huge problem:
When I started a DVD player it complained that my DVD drive is not
using
DMA!
I went to the DVD device setting and noticed that it is on PIO (with
autoselect).

The DVD drive: Creative DVD6240E

What could be wrong here?
Why did XP change its mind?
