Can either of those formats even successfully be muxed into an MPEG-TS?
SRT shouldn't work at all, I wonder why ffmpeg doesn't refuse to do so.
I was under the impression (from personal experience, not standards)
that dvdsub shouldn't work, but dvbsub should. Caveat: ffmpeg could
have problems of its own with the latter, see trac #2024.
