Just out of curiosity, did the BDP-S380 receive a firmware update that enabled DLNA support? Every review/description I've read states that it lacks DLNA support.
Mezzmo has been fine on my Sony BDP-S380 until this most recent update. Now the server won't even start on the device.

Mezzmo is the only software I've found that can properly transcode Nikon .mov files.
