Sources Property (IMediaControl)
A collection of all media file source URLs.
Remarks

A media file may have multiple URL addresses for use in different browser types.

If the src attribute was set, but no sources were defined in the HTML, the Sources property will return a collection containing a single item with the "src" value.
