Hello There, I am running OS 10.3.9 and have I have Quicktime 7.1.3 . The other day someone sent me a very funny video clip as a wmv. file. It opened and played in Quicktime but now Quicktime tells me it can't open the file. I thought maybe I had altered the video file in some way so I got my friend to resend it but alas I can't open it. Any ideas?
