I'm trying to play a few of the rock riffs on this video but I can't seem to get them, the tuning i'm in is DADADD, cause that's what I thought it was, but something tells me its not.

What tuning is it and how is the riff played?
thanks in advance guys.

But the first 4 chords seem to be in DAD

D---3/5--5/6--5-7
A---3/5--5/6--3-5
D---3/5--5/6------

But the couple of double stops/chords he strikes next I cant seem to get.
