Can't see anything in Doom 3 trailer

I've just downloaded the Doom 3 trailer with extra footage and, I can't see anything?. I can hear the action but why can't I see anything?

Just a guess (I don't even know what format the trailer is in), but it sounds like you probably don't have the latest version of DivX.

divx.com

yea eather that or you dont have the latest drivers or quicktime because thats what my problem was and I downloaded a new version and bang back in buisness :).

You should have seen that one coming, what with your psychic powers 'n all. ;)

Your either:

a) Missing a codec or
b) Using Windows Media Player 9

WMP 9 has a bug that causes this to happen sometimes. If this is the case, then just keep trying to watch it until it works, or get another media player.
