When Windows Media player goes to play the Alderaan clip, all I get is the sound track...no pic...

It quickly flashes something about codex on the screen and goes right into the playing of the sounds only.

Can somebody help me?

Try downloading a program called "GSpot" from here. Once it's installed, you can use the program to open the file in question, and it should tell you what codec(s) it requires to run. A quick Google search from there will then probably land you the missing codec(s).
