This sounds like it's causing you a headache shauny.
By the sounds of you do not have lan access but wish to put the movies on to external hard disks and then play them from the dune right?
Could you please do a little structure of what you are trying to acheive
ie
Dune > USB external drive fopr movies
Dune > Internal HDD for MKV's
etc
Your test is very long and a bit of a headache for me to read.
I am by m=no means an expert as I was the one asking the questions in the first place here. If I can help I will though.
