I used the GOUT v3 ESB video, I could use the 2004 DVD's instead, that would look much better, but then we will be sync'ing to the SE and not Theatrical, which to me makes no difference, I would use the better video, I am NOT a Theatrical only guy, I like ALL versions.
Let me know what version you want to use, because obviously I will have to get you audio that is in sync to that version.
