Topic: Subtitles doesn't work correctly on DVD's

I usually make dvd-rips with makemkv and watch them via mpc and svp, but suddenly the subtitles on DVD has stopped working, they usually work nicely 5 minutes after movie and then vanishes. What would cause that?

I have win 8.1 64bit
amd radeon 7950 and latest 14.9 drivers.

... and why exactly you think it is related to SVP?

I am not sure smile was about that maybe you could hint that what would cause the problem as SVP provides all the necessary components to watch DVD:s, including the player, madVR, SVP, ffdshow and reclock, so actually SVP containts all those and can be named to relate to a SVP.
