He has nearly zero computer knowledge! And because i can't go over his house i have to tell him everything from the phone! And its not that easy to explain these things over the phone, especially when he doesn't have a clue of what the hell i'm telling him to do lol so this is what the hell i wrong with him!

Anw.. problem solved.. i just told him to throw away the damn DVD and i made him another one that was working!

VLC or klite codec pack, a greased out toilet roll and a box of Man Sized Tissues is what your friend needs.
