Unfortunately we also don't have lots of spare time, that is why the
developing has stalled in the past time.
On the other hand, we are almost there... We can watch live-tv, record,
playback and also time-shifting works. But there are still things to be
done, it is not as stable as it should be, and the build process is
difficult and almost completely undocumented (especially for the
mminput-plugin)

Yes, that should be fine...

Hmm, you can check with ipcs if the shared memory block has properly
been created, has the correct Id (it should be the one in shm-common.h),
and has the correct size. If you end the vdr, the block won't be
deleted, so you may try to delete the shared memory block and let vdr
create a new one. Did you make sure that you have a clean build (make
clean doesn't delete all the files...)?

Bye,
Martin
