Don't know the how much it will affect Emby but TVDB is having issues. So if you are having issues with TV Series/Episodes, this is more then likely the issue.

I know this is affecting Media Center Master. With a little testing in Emby I see Identify by TVDB id is failing here also.
Guess that time is coming closer, what is the actual progress on this? And the v4 API implementation? Will it be system-wide or subscription based? Or any alternatives will come in play? I don't mind paying dollar-a-month, but at the moment have no idea about the actual vision Dev team is having.
Thanks
