I will warn you guys now - the way newer cutscenes are coded is different than how the old ones were done. To prevent people from cutscene-bombing, it now renders the scene in a new 'instance' as it were, and if our characters appear, it's done as doppelgangers.
What this means is, sometimes when you play back the newer ones, there's nothing there - it's because you are now further away than the camera will register. To offset that, what I often do (and JUST for the cutscenes) is edit my POS to about ten feet under the focus of the cutscene (Mother Mayhem, Marauder, whatever) and then replay it. Voila, now I'm in range.
Stuff like the shifting focus that the REALLY new cutscenes have does not render, unfortunately.
