Errrm, search the list for the post in which I (and others) have asked
the question whether we could possibly fund some time to get it fixed
up - once you've found it then you can go ahead and make comment on my
problem with reality. Until then, is there a need to be quite so

We're not all expert C coders, some of us are hackers or scripters,
some of us can't code at all. Given the lack of support in H264 in
FFMPEG I managed to hack something together to assist with the
implementation of CoreAVC in xine for VDR but that's about the extent
of my skill. Was it fun trying to extract resolutions from H264 SPS?
Not really, but a whole lot more people can now watch H264 channels
with VDR now...

No, I agree. Which is why I mentioned that if we could only find the
problem with the spatial direct mode we'd  more than like be 99%
