Likely. Video output driver directx should disable Aero. Use video output driver direct3d if Aero is absolutely needed. You could also use video output driver GL, but it is not stable with most hardware under Windows.

Is that why -vo vdpau -vc ffh264 works but -vo vdpau -vc ffh264vdpau doesn't?

DXVA, DXVA2, VDPAU, and VA-API (GPU acceleration) will not decode Hi10p. Not at least until there is a GPU hardware update to support Hi10p. Linux (PC) users should use video output driver GL when possible; XV if more performance is needed and/or if screen tearing is present on multimonitor setups.
Edit:
Using -vo vdpau -vc ffh264 will be better than running -vo xv in subtitles as they will render to your desktop resolution and there should be no screen tearing present. Video output driver vdpau should however not be used if using compositing (Compiz). -vo xv will provide greater video performance though, being that -vo vdpau -vc ffh264 will perform similar to -vo gl.
