Sorry about the quick reply. Quite busy at present.
As nikki said, you can move the player around as if it were the camera, I don't know how easy it is to manipulate the players view (Where is looking) however, it is (I think) possible to do with MGE. (It may be possible to do with vanilla MW

)
However, if you are going to do this, a lot more foolproof method is to record a video with FAPS or whatever, and then convert it to a bik (Using free tools) and then just use MW to play that. That way it will work as you want it every time, without needing a huge amount of scripting.
I was thinking about video with the player doing things, and it suddenly gets very complicated (although it would be a lot easier using OBs scripting engine)
For Morrowind, I had a couple of thoughts.
Move the player around using keypresses, you can do this with MGE. It would however be hard and annoying to do, and the end result wouldn't look good.
Another option is to place a duplicate of the player (
placeatpc, playersavegame, 1, 1, 1 (IIRC)) and move that around. I have never tried manipulating the duplicate, and it does have some drawbacks. The duplicate is (IIRC), a clone of the PC from the last save, or from when the game was loaded. You may be able to get MGE to press F5 and (If required) F9 to get the most recent version. It will also vanish on loading, with would have to be taken into accound.
I have never seen the clone of the player manipulated, though it should be possible, even if MWSE is required to deal with the exact ref.
You could then manipulate the clone, and move the real player around in the way that nikki suggested as a camera. That way you could see yourself talking, fighting, whatever. Which would be really cool

.
I would be interested to see if anyone else had some thoughts...
Loads of mistakes in the above probably, but got to to back to RL.... Maybe more later.
