1722,PGS subtitles vanish/disappear immediately in m2ts,skank,,"PGS subtitles vanish/disappear immediately after shown.. in m2ts files..

This is quite an urgent problems as none of the blurays with it, play subtitles well..
Its only an ffmpeg issue cause the same thing plays well on powerdvd, Total media theater, MPC-HC ,...
To test, you should use xbmcplayer or VLC player (as both are using ffmpeg) not something else
