This is an incompatibility caused by the packager not updating Xorg and
libdrm at the same time. With xorg 7.0 RC2 and libdrm 1.0.5 this should be
resolved.

This seems strange. In particular that nobody has reported this before,
and libXvMCW has been used extensively. I'll take a look.

I think Luc has filed a bug about this at Xorg.

Do you see this with the Xv plugin as well or only with the xxmc plugin?

I'll have a look at this as well.
