Clips problem

I am using Windows Media Player to watch mpg., mpeg., ram., rm., wmv.. Sometimes the WMV. will download, but when I try to play it it won't play. The clip from Silver Cherry Productions and the clip from Get The Secratery are two that do this. They download fine, but when I try to play them a box pops up that says, 'Windows Media Player cannot play the selected file because it is either damaged or corrupt. Please select another file.' I know there isn't a problem with the file because everyone else is watching them fine. I've tried re-installing my Player, but it didn't help. Are there any extentions or scripts that I might not have that I need? I'd really apreciate any help.

You might try playing them on Quicktime or Real Player....both free DLs.
