I can not see my new files on my Computer from apple tv

I have downloaded some new movies and cannot see the files from my computer. I can only see the movies i had when i first installed the atv on my apple tv . any help would be appreciated 

Hi, I had this problem, it is not clear in the instructions (but it is there!) - set mine up this afternoon.

 

If you have a Mac go to System Preferences (under the Apple sign in the menu bar), then click on Sharing.  Make sure File Sharing is ticked and add a folder (say Downloads) that you want to share.  Make sure Everyone  in the users box (or whoever you want to share) has at least Read access.

If you use Windows the instructions are here.

Hope that helps.
