Sadly atleast this is not the case, (with libdvdnav atleast) still images
without sound do have a proper indication DVDNAV_STILL, but still images
where the sound keeps on does not. Here the video just suddenly ends with a
eof group seq.

I technically don't have any issue with this at the moment, as we're using
libmpeg2 instead. Aslong as the parser in demuxer let's out the data (which
was the problem previously, but now fiex), I get the last frame as
expected.

I haven't actually tested libavcodec as decoder for dvd's for quite some
time. It just struc me as a potential problem.
