Sound from DVD drive warbles.

[mccanute]

When I play a CD or DVD in my DVD drive the sound has begun to warble
rythmically, with like 5 "beats" per second.
It may have started when I installed a new drive with Light Scribe and all,
but then I replaced it with the old drive and the warble is still there.
The video part is not affected.
Sound files, whether wav or mp3 played back from the HD sound OK.
Windows is XP Pro SP2.

Does anyone know about this phenomenon and how to get rid of it?

Perhaps a setting in your "advanced" sound card software? I know older
creative labs cards had various "presets" you could apply.

Thanks Bob,
It says standard unit is SoundMax Digital Audio, I've been into some
"advanced Settings" there and fiddled around, but so far it has not had any
effect.
My PC is a Dell Dimension 5000, about 2 years old now, it's not state of the
art, I know, but not too old or weak either, although it could probably use
some sound and vid upgrades along the way.

I am new to this forum and accidentally first placed the post under "Windows
XP Media Center Edition" (sorry, I shall try to move it here) and got an
answer that referred me to http://winhlp.com/node/10, a good one, but my
Primary IDE Channel properties says that the state is Ultra DMA, so there
shouldn't be anything wrong there.

I get this idea that maybe something else is trying to access the memory at
the same time. Or is that too far-fetched?
I just don't know how to look for the culprit. Is there some tool out there
(or in my PC that can analyze events?

Thanks
