While I was trying to sync subtitles to an mkv file, I found that each time I played the same file, audio seemed to shift a few seconds. So the same sentence was spoken at 01:06:24, the next at 01:06:22 and then again at 01:06:26.
That makes it impossible to sync subtitles and audio. At first it seemed audio was off only in Subtitle Workshop 2.51, but I later found it also happened in MPC-HC (Nightly) 184.108.40.206 (0d2d2d2), with FFmpeg compiler MinGW-w64 GCC 4.8.2.
How is it possible that audio is not reproduced in exactly the same manner each time? I tried looking up this phenomenon on this forum, but I didn't find it, which may have to do with the fact I didn't use the right search terms.
Anybody any idea?

There are no audio sync issues, so it seems that the movie is sometimes a bit faster, and sometimes slower. I'll try and see what happens with VLC. It happens with a few more movies (only mkv). It's not a big deal, I'm just curious what can cause the phenomenon.
I'll also try and use Subtitle Edit to see what happens.
