Comment (by mikecheat04):

 I see. Could any of the code from the libzvbi project maybe help with
 this? It seems they've found a way to gather that information from the
 video stream and then mux it into a TS. There is also another project
 called OB-Encoder, they use libav, libx264, and libzvbi with a third party
 mpegts muxer to produce the desired output. I could use their program but
 they don't currently support mpeg2 and some of the more advance features
 of ffmepg that I've accustomed to.

 libzvbi - http://zapping.sourceforge.net/ZVBI/Download.html
 obencoder - http://code.google.com/p/open-broadcast-encoder/downloads/list
