Somehow you got it mixed up.

The DVB API headers in the kernel are older. The stuff in the kernel
will be updated when the problems with i2c vs. frontend firmware loading
are resolved. And the stuff in /usr/include/linux will be updated later,
when your distribution gets a glibc built with the new kernel headers.

Meanwhile, if you want to compile bleeding edge vdr plugins you need to
copy osd.h from the driver to /usr/include/linux/dvb/. That's all.
If you say vdr doesn't compile with that, then post the actual
compiler error messages.
