Mark as watched over DLNA

Hi,

I believe this might be a bug:

I use Plex on my Mac as server and consume content from my LG TV over DLNA, but once I've completed to watch a video, it doesn't mark as watched automatically. Instead I have to go to the server site and do it manually. Shouldn't it do it itself?

Plex server version: 0.9.9.13 on Macbook Pro 13"

TV LG 42LM660S 

Thank you
