Sounds like the mkv contains VFR (Variable FrameRate) video. When you assume that the video is CFR like that then it is not supposed to sync.

Been a few posts lately on VFR MKV's, so you might want to try searching.

you could try mkv2vfr from http://haali.cs.msu.ru/mkv/.
It is a command line tool, open a command prompt and type
"c:\location to\mk2vfr.exe" "c:\video.mkv" "c:\video.avi" "c:\video.vfr"
