    Closed captions are part of the MPEG stream.

    This is why you will lose them if you transcode the MPEG stream to 
something else. I use a utility to extract the CCs for any movie that
I transcode. If you have an MPEG stream embedded into an mkv container
then the data should still be intact.

     That and your 18 other extra language and subtitle tracks.
