Local files on SPMC

Hey all

Just got a nVidia Shield and installed SPMC on it. So far so good but the problem I have is I can’t add my 2 HDDs loaded with movies, TV Shows and mucic to my library. I looked all over in my SPMC settings when I go to add videos>Browse….nothing to be found that leads to my HDDs. I am sure it is a simple setting I am missing but I just can’t find it.

When I click on Root, nothing opens. I assume it is not rooted and being that is it brand new, I really don’t want to root it.

Please help me find my way to my local content.

Thanks

RR
