DVD skips on playback since installing SP2

Archived from groups: microsoft.public.windowsxp.video (More info?)

Hi all - I just downloaded and installed service pack 2 for Windows XP
Home. When using Windows Media Player 9 or Real Player 10 to play DVDs, I
encounter a one- or two-second "skip" every so often. The DVDs are for a
class I'm taking through a distance-learning program, and when the "skip"
occurs, I lose about one or two seconds of the lecture.

This started happening right after I installed SP2, so I used System Restore
and undid the install. Sure enough, the skipping went away. I reinstalled
SP2, and the skipping returned.

Has anybody else encountered this problem? Anybody have a solution?

Thanks much,
Kevin
