WMP problems

hi

i am experiencing problems playing AVI and MPEG files in WMP.. it also seems to prevent me opening MOV of MPEG4 files from in Quicktime Player.

the error message is ” the codec used to compress the file cannot be found”

i do have the K-lite Codec pack installed and im runing FFDshow but i could have possibly not configured it correctly

does anyone know how to configure it so i dont experience these problems?

thanks
