Be aware that the Russian firmware does not include the media server as part of the normal update firmware process. To add the media server you must go back to the web site and follow the instructions there to add media server. Unfortunately (for me at least) the instructions are not simple enough. You must have in depth technical knowledge of which of many files to download, install, and modify before you can get media server functionality.
If someone here (Gary?) could simplify which instructions to follow I would like to try, since I installed the firmware update and found it to be stable and fast. Unfortunately I use the media server with my WD box to display photos and videos from my library on the TV.
