Movie Trailer

Hi all

Not to sure if this is the right place to post this but I am using the default skin which kodi 17 installed.

I am trying to get my local trailers to play but when I hit the trailer button on the info screen it does not play. I do have the right naming

move.mkv
movie-trailer.mp4

I even tried ember which puts a line in the info file

<trailer>\\SERVER\*********\************)\movie-trailer.mp4</trailer>

but it still does not play am I missing something ? I can get the trailer to work with youtube but I don’t want to use the internet and would like to play my local trailers which I have stored.

any help thanks
