I need to encode some content as an MPEG2 transport stream for playback on a professional grade DVR for a museum kiosk. We'll need captioning for hearing impaired. Is there a way to mux in the .cc or .scc files? I've inlcluded them when authoring DVDs in DVDSP so I figure they must get muxed into the ts as opposed to residing in the elementary stream. How can I do this outside of a DVD authoring program so I can have better control over the final output? I currently use MPEG Stream Clip but couldn't find anything in that app regarding closed captioning.
