Just to clarify, there are two different Dirac implementations, and two 
different theora decoder implementations. But otherwise your points 
stand. There are many implementations of the mpeg codecs.

I'm not sure how many separate implementations ther are of the Windows 
Media codecs. FFMPEG has a VC-1 implementation and some decoders for
older formats based on reverse-engineering.
