Following up on this issue, after several months of chasing this, I finally got through to somebody in Samsung that actually understood the problem AND spoke English (will wonders never cease).
Apparently, Samsung engineering is aware of this issue, but does not consider it to be sufficiently prevalent to actually create a solution. Also, they do not seem to have any specific plans to include this functionality in new versions of their equipment.
Their focus (as it was generally explained) for Blu-Ray players seems to be on streaming media and Blu-Ray disks. The DLNA they provide is a sideline that “meets the DLNA standards…”.
So… in the absence of reliable interface information as to what works and what does not, I am chalking this media server idea up to a general waste of time, since the DLNA standard does not seem to provide a reliable connection. It is a shame, it seemed like such a great solution.
My WD My Cloud will be re-tasked as a general back up drive.
