it's hosted by mplayer, nothing relation to (open)quicktime4linux

yep :(
but worth to do it...
if real is done, then only sorenson left...
with it, mplayer could play everything!

sure, but i don't know more
let's see what are there...

win32/vfw, win32/dshow, win32/acm - implemented by avifile guys
xanim binary codec plugins - implemented by alex
openquicktime binary codec plugins - should be easy, but has no sense, the
  only such codec is 3ivx, but there is 3ivx for xanim too
realmedia codecs - you know ;)
win32/quicktime codecs - see above
winamp audio plugins - under development

sure there are other programs having some codecs in separated .dll form, but
they aren't interesting for us now. maybe that blink video stuff, used by
windows game intros, but i have no clue nor interest how to support it...

maybe - but i'm not sure how separated is it - the DTS audio decoder from
powerdvd... some DVD disks use DTS audio but no free dts implementation (nor
docs on format) available
