This is weird.

I applied this on top of my WIP ARIB branch
(https://github.com/jeeb/ffmpeg/commits/mpegts_arib_stuff) and now I
lost service name / provider altogether...
I mean, the stuff in the branch is "quick and dirty" at this point,
but it's still peculiar.

This can be seen with both the PID switch sample I recently posted as
well as with the ARIB captions sample I posted in the libaribb24
wrapper thread.
