Furthermore, I am unable to compile in any more deinterlace filters,
even if PP_LIBAVCODEC=1 is present in the makefile. libpostproc.a is in
the correct location and everything compiles successfully, they are just
not available in the setup menu.
I succeded now in compiling softdevice with PP_LIBAVCODEC=1 after doing
make SHARED_PP=1 in xine's libpostproc dirctory and as written in the
Makefile, but I as well only have in Menu -> Deinterlace Method the 3
things that were there before, and now while switching them vdr crashes.
