I had a short look at this patch:

A minor cosmetic thing: the '#' of pre-processor directives should always
be located at the first column of the line.  You can add spaces after
the '#' if you want to indent the directives.  This is probably not a
problem, if VDR is only compiled with GCC.  At least the compiler on
SGI IRIX (r.i.p.) would choke on such code.

A more important suggestion: Could you please add a notification method
to status.h for notifying plugins whether VDR is currently in
interactive mode?  This would be useful for at least these three
plugins: softdevice, subtitles, and relay (my own plugin for controlling
a solid-state relay that powers the display on or off).  Here are the
relevant chunks from my suspend patch
<http://www.iki.fi/~msmakela/software/vdr/#suspend>, which is to my
knowledge included in some VDR distributions:

I'd suggest a method SetInteractive(bool Interactive).  When VDR is
in non-interactive mode, the display would be powered off and the
software decoding of video would be suspended.  For full-featured
cards, the suspendoutput plugin could perhaps be adapted:

If you implemented the method, it would make my vdr-suspend patch
unnecessary.  I could then try your patch and adapt the three
plugins I use (relay, softdevice, and subtitles, in that order).
