One of my friends gave a *.MKV file, and I had no idea what on earth it was till now. It really does look quite interesting as its a direct rivial to Mov, Rm, Ogg and Avi, so it can contain xvid, divx and what ever codec you like. It was also built out of the really nice EBML open standard The filter is available here or better still here and its GNU. Nice…
