On the flip side, I remember installing a PNG datatype and then suddenly every single browser could display PNGs, whether the browser author cared (or even knew about) PNG or not.
That's great, but what are websites supposed to do? Start serving up PNGs (or whatever modern equivalent) and hope that users have the correct plugin? Or do they stick with something not quite as good that they know will work? That is why having a small list of supported codecs is important (leaving aside the fact that many users simply cannot install additional software).
Nobody cares about Matroska files except for pirates (which is a shame, because it has nice features). Neither Windows or MacOSX are interested in supporting every single codec under the sun. You can install additional codecs for both Windows and Quicktime if you want to, but if you are distributing files it is better to just use an industry standard like h264. This is exactly my point.
