The first bug also showed up on the "MOST RECENT ACTIVITY" section of http://channel9.msdn.com/Forums/

"Passing mms:// url to embeede… player on web page in asp.net"

However it displays correctly on the actual post ( http://channel9.msdn.com/forums/TechOff/464489-Passing-mms-url-to-embeeded-windows-media-player-on-web-page-in-aspnet/ )

... but I imagine these things all have a single root cause.
