Ah! You might have answered another question that's been troubling me.

I tried everything to connect directly the VMR9, but there's always a Colour
Space Converter inserted between my output pin and the VMR9, even when the
subtype is ARGB32 and every conceivable range of format is used. Is it
because I'm trying to force my Allocator upon it?

Yes, that would explain what you're seeing. I ran into the same thing
when I tried to connect an infinite pin tee filter to a VMR. They both
insisted on using their own allocator, so a color space converter was
inserted between them because they couldn't agree on the allocator.
