On one of my PCs the sound skips when playing a DVD. The sound seems to stop for a second and then continue. This does not affect the audio/video sync and the video seems to be unaffected during the skip. This will usually happen once every few minutes. I cannot replicate this on my other PC. Other media players are fine (VLC for example). I'm not sure what log files would be helpful. I would be happy to look further into this.
