Hi,
BRCM-DMS:2 is a file-sharing functionality built into a video/ audio player.
This concern is more complex than what is typically answered in this forum. Since it is most likely that this is more of an engineering issue,it would be best to redirect you to a dedicated team that may have an in-depth knowledge about it. Please check Microsoft Development Network Forum (MSDN).
For additional reference, you may also check BRCM-DMS:2 HEY MICROSOFT- WE NEED A REAL ANSWER!!! What is this??.
