Black border arounds WMV files

[greenoak]

Whenever I add a wmv file into my powerpoint ( 2003 ) slide I get a large 1 cm black border around the image. My slide templates are mainly white and the black border is very ugly.

How can i get rid of this or change it to white so it is masked

The movie files were created with Adobe premiere Elements and used the 640 x 320 setting.

Thanks

I haven't been able to find a method to change this either.

But I did read a clever suggestion in Garr Reynolds, "Presentation Zen Design".
He took a graphic of a tv with a transparent screen and played the video behind it, so that the video played on the tv.
