Well, there's a difference that has already been pointed out on the
list: with a patch (even against the most recent FFmpeg's mainline)
you have an issue of bitrot and maintenance. Once the changes
actually get accepted into the repository you have them there
for eternity (either that, or till somebody rewrites the whole
thing from scratch). The later is much more desirable (and difficult!)
than the former.

It is actually 100% synchronized now. My intent is to constantly
update it (and thanks to Git that is not all that difficult) so
that everytime you do: 
   $ git diff master dans-patch
you get the patch that is applicable to the FFmpeg's mainline.

Please do. That'll help me a great deal. Currently I only have *p50
samples (which is pretty ironic given that I'm in NTSC land myself).

I was recently contacted by Troy James Sobotka <troy.sobotka at gmail.com>
who seems to be very interested and motivated to help as well. I'm
CCing him to see what he is up to ;-)
