SYMPTOMS

Playback of .avi files may skip and stutter. The problem seems to occur more frequently when you play back the content from a CD-ROM device.

CAUSE

The DMO filter, which is used for DirectShow and Microsoft Windows Media file types, allocates audio buffers 2 seconds long. This occurs to make sure that there is enough audio in the buffer for the Windows Media SDK to use if a specific video frame takes an unusually long time to process. However, DirectShow file types do not require this long of a buffer. In the case of the .avi files, the AVI splitter loses track of how much audio has been delivered.
