Keynote presentations with embedded videos

[smackwarm]

So I'm writing a keynote presentation and exporting it to powerpoint when I'm done, but it won't let me add a video that's got 2 compatible formats, i.e. keynote will only accept .mov files and powerpoint will only accept .wmv files. As I'm gonna be playing the presentation on windows, is there any way I can get the .wmv file into the keynote presentation? Cheers
