I didn't give it a full go but I added the nut file and the folder as is and got nothing. Is this specific to the newer AM build? (I'm currently on 2.3)
I can see the menu pop up and I tried various versions of where the files are(/4x3, \4x3, 4x3) but AM launches and no video plays.
I'll try it out again and see if it's something I missed.
