Okay, I download the codec and it worked finally. A few bits at the beginning are still a bit choppy but past the planet its alright. On the whole it looks pretty cool. My favourite part of the trailer is where the battleship type unit is shown firing volleys off to its starboard side while it turns. That looks pretty cool. It'd be nice to see some more ship to ship combat, or bombing runs or the like.
Btw, I got the impression that you may be using the "Dive, Dive, Dive Hit your burners pilot" bit for a built-in wingman "watch your six" type of message. I would recommend that no one ever used that wav for such a purpose, as after the sixth one in a mission it would get rather annoying. (you probably have no intention of using the wav file for that purpose, but just in case . . .)
