VLC 0.9.4 problem synchronyzing subtites (*.sub)

Hi all. I have problem with timing *.sub subtitles. From beginning seems timing ok, but then subtitles shows faster as film goes (and I be afraid that shift isn't constant). I try then films with *.crt and here it looks OK. Can someone help me with *.sub problem? ... Maybe only sub converter solve this.

Thanks for reply.

p.r.: In 0.8.6f were films with *.sub OK.
