[mythtv-users] Naming conventions?

[Greg]

  I was given Law and order UK season 1 as a gift... I ripped the 
episodes to mkv's..I gave them the usual name Law and Order :UK 
s01e01.mkv. It won't download the metadata..I looked on the TVDB and 
there is covers and fan art....

I have tried:  Law & Order :UK s01e01.mkv,Law and Order UK 
s01e01.mkv,Law and Order :UK (2009 s01e01.mkv

Does anyone have an idea what I am missing?
