In this sample file subtitles are shown on wrong side of the screen (left in the middle and not at the bottom) (you have to enable it if they are not shown). I know that in older versions it was playing fine but can not say when.
Using omx player.

I can see the problem but it's no pi specific. It behaves the same with a master build on x86/linux. Might be worth reporting here:
