Cross browser accessing markers in an embedded video

hi

I have a video (.wmv) that has markers in it
one can access these markers in video players like “Windows Media Player” at “view” -> “file markers”

I want to embed the video object in an HTML page and be able to let the user jump to these markers via JavaScript or such.
I managed to do this with Internet Explorer ודןמע JavaScript but I can’t get any other browser to access these markers or any timeline

function for that matter.
I need to be able to do so cross browser.

any ideas?
