I'm less sure about this one, but I think it's similarly necessary for some codecs; in particular WMA/WMV comes to mind.

For what it's worth, I think it would be possible without too much difficulty to compile by hand a list of formats that Windows supports natively; we don't strictly need to provide any others for the purposes of emulation. (On the other hand, some applications that use quartz are generic media players, and a user may want to be able to play, say, Ogg audio, which I don't think Windows supports, using a win32 media player. But then maybe it's their responsibility to install the GStreamer plugins that they need.)
