xine-lib must be patched, patch for this you can found on xine plug in directory. It add connection between vdr&xine
no need any patches for xine-lib-1.2 and xine-lib-1.2-vdpau branches
Except this xineliboutput plug in with external frontend (vdr-sxfe included in this plugin) it more useful a don't have problems with jumping on video&sound.
I have another problem when ANY version of xine&VDPAU drop video frames. Some HW is better, some is worst. It happen when PC is under heavy load (example compilation on background).
run xine (vdr-sxfe) with "nice -n -20" help little bit but problem still exist.
Worst situation is HD 1080i video on integrated Nv6300, it drop around 90% of frames.
Yes, I am sure that VDPAU is used, and I am not use any video filter except deinterlacer in VDPAU.
