Both XII and BWB are bad about having issues with their releases.  They won't stream to xbox360, play on standalone (DivX enabled) DVD Players, or many computer media players.

Get [url=http&#58;//divfixpp&#46;sourceforge&#46;net/:13s9gn9h]DivFix++[/url:13s9gn9h] to fix this issue.  This is for the standard .avi releases, may not work on the 720p .mkv releases.
