That is actually what I meant by "current FFmpeg svn trunk" -- the
actual FFmpeg mainline that everyone uses if they checkout FFmpeg from
the FFmpeg project pages.  The experimental branch you have seems a
bit out of date compared to mainline FFmpeg -- making it easier to
integrate various patches, but harder to make a clean patch against
mainline FFmpeg.

I'll see if I can generate one of each of these formats sometime today
or tomorrow.  AFAICT, there's more possibilities of formats, but
hopefully these are all that might be seen in the wild.

I'll keep this in mind.  If there's any other developers out there
whose companies would like to see DVCPRO-HD integrated, I could
probably get a bounty page set up to collect more pledges for support.

I'll check it out; if I can help with the creation of a mainline
patch, I would love to do so.
