Hi, I'm new member of this forum. I have a problem witch WM11. I'm using vista home premium. My WM11 can not play a type file with error "Windows Media Player cannot play the file (or cannot play either the audio or video portion of the file) because the Microsoft MPEG-1 (50) codec is not installed on your computer." . And I installed Vista codec package v4.4.5, but I don't know the way to use it. Please help me !!!!!!!!!!.
