Wmp 10 and mpeg

Hi

i've got a problem

i have wmp10.. and i can't play mpeg1 files with wmp... it works with windows media player classic or vlc media player.. but not with wmp.

But the strange thing is that the same file plays on streaming in wmp... but doesnt play if i download it and try to play it from my hdd ..

nosense :O

Anyone have an idea of what 2 do to fix the problem ?

Does WMP 10 recognise the file at all? What is the error you see? It could be a missing codec.
