SYMPTOMS

When you use Windows Media Player to play MPEG-2 video content that is standard definition (SD) video-compliant, you encounter a display issue on a Windows Vista-based computer. Specifically, the content's 16:9 aspect ratio is unexpectedly displayed at a 4:3 aspect ratio.

CAUSE

This problem occurs because the Microsoft MPEG-2 video decoder does not recognize the sequence display extension in an MPEG-2 video stream that is produced by an SD video camcorder.
