Comment:

 I am not sure I understand you correctly. You mean that:
 * xbmcplayer and VLC have the problem;
 * powerdvd, Total media theater, MPC-HC (not ffmpeg-based) do not have the
 problem;
 is that it?

 On the other hand, MPlayer, which is also ffmpeg-based, displays the
 subtitles correctly.

 There are known problems with the PGS decoder, especially with timing.
