- if you are using power DVD   See if in the options/advanced options of PowerDVD if there are any checkboxes for hardware video or audio acceleration. These can make the difference between smooth playback or stuttering/glitching audio.

I'd also make sure your video drivers are current, AGP is working properly (if an AGP video card) and you have the latest video drivers. In most cases, stuttering sound is due to the inability to sync audio since there isn't enough CPU resources to do this after video decode. If you can somehow reduce CPU load, this will usually clean-up audio problems.

Low memory conditions, trojans, spyware or incorrectly configured/too many systray applications can also do this. I'd try disabling any extra systray tools/utilities and messengers as well to make sure these aren't messing up dvd playback. The Task Manager should also be helpful for sorting by CPU utilization to see what might be taking up unnecessary CPU time, as well as inspecting how much available memory is free on your system prior to launching your DVD application.

- windows has its own drivers installed already
for the cd and dvd drives.
