You have to enable VDPAU output as well.
Sorry, but where and how? In VLC? *.conf file?
If you don't do that, in case the readback method is used,
I read something about it. Can I disable 'readback method' as interrims solution?
it won't work because the necessary format conversions have not been implemented yet (I'm working on it).
Go ahead ;-)
