GSoC=Google Summer of Code ?!

I saw the subtitle displayed o.k in mpv, vlc shows them, but too small and I can't figure out why yet. Xine plays the resulting file without subtitle and audio video out of sync ...
Is there any possibility known to use another subtitle codec? The mkv-container would be useful, but in half of my tries conversion from ts to mkv fails with audio/video using codec copy. I found many hints to this but to my knwoledge it is still a game of luck.

Yes, these options results from fooling around with other problems, besides from "prefix" to preserve the ffmpeg supplied by my linux distribution in some rare cases I just forgot to remove them long ago.

Kind regards
