I have been playing around with various settings for capture with ATI's latest version of MMC - 7.6. However I see that the WMA format of captures are "greyed out" and I can't select any of them. I assume that this means I don't have the correct codec on my system. I would have thought that ATI would have supplied it with the full install of MMC, but obviously not.

Which is the best codec to install? Anything of the Microsoft site? Or are there alternatives?
