No WMV support in CS4?

I have the CS4 trial and can’t encode WMV - I’ve tried through the Flash Studio and the Media Encoder. Any ideas why? I could on Flash 8, which was the version I used to have. I have bought the full version of Design Premium CS4 which is arriving Monday so I wonder whether installing the full version will help. I doubt it though.

I’m on a Mac if that makes a difference (I know the Windows video support isn’t good with Apple).

I’m in trouble if I can’t sort it as I work for an agency that give me .wmvs. :cantlook:
