In Microsoft Windows Media Player 10, when you play back Windows Media Digital Rights Management (WMDRM) protected content, the script commands in an embedded script stream may not fire as expected. If the content is not WMDRM-protected, the script commands work fine.

This problem occurs because Windows Media Player incorrectly detects the script commands as being invalid.
