user_data packets are part of the mpeg2 standard.  DVDs can include closed
captioning data in these user_data packets.  I think perhaps other mpeg2 source
may do similar but I'm not sure.  And I have no idea what the general way to
handle that data is for arbitrary streams.  When mpeg2dec element still
supported user_data output I had a little DVD test to decode those packets with
the vbidec element and print the CC data to the console.  I was thinking future
DVD players would use that functionality along with text overlay elements to
provide good closed captioning support.
