Have your patches been merged yet? When will they be merged into the xine-lib-1.2 tree? I don't know anyone still using 1.1 since 1.2 is where the vdpau dev happens.
Yes, the patches have now all been merged into the xine-lib tree:
http://hg.debian.org/hg/xine-lib/xine-lib
I suspect that the patches will also arrive in the 1.2 tree at some later point. However, xine-lib-1.2 doesn't build for me on Fedora 15 so I can't test it myself.
Cheers, Chris
