I have 720x576, 16:9, wmv embedded into a page

on computer with WMP11 it plays fine in 16:9
but on computer with WMP9 the very same video playes in 4:3? (if i play it locally with the system's WMP9 it plays it 16:9, there is also media player classic installed on thsi PC and it plays it 4:3, is it possible the installtion of media player classic to messes up the things?)

So, is there a way to force 16:9 into the older versions?
I searched for such embedding parameter, but didnt find anything similar


p.s.
also im noticing that the embedded video size is significantly smaller that the video window size when played locally, even if the dimensions of the video are set right in the embedded page
