[Ron Johnson]

Public bug reported:

On this page:
http://blogs.msdn.com/b/b8/archive/2012/05/09/redesigning-chkdsk-and-the-new-ntfs-health-model.aspx

is this link:

Clicking on it blanks the window except for the normal set of media
controls except that they are *at the top* of the window except at the
bottom as usual.

Clicking on the Caret in the upper right of the screen and selecting
Full Screen shows the video and the audio properly.  In Full Screen
mode, of course...

On my wife's Maverick computer with FF 11, the video plays but not the
audio.
