Hello,
the vdr-addon (vdr core application) suffers from an old bug which causes a segfault when i switch to "N-TV HD", a scrambled german news channel.
There is a patch floating around for vdr 2.2.0 since january 2016 which made it already to the most vdr based distributions (eg. yaVDR).
Would be nice if you could apply it to the next build.
