[Matroska-users] Matroska doesn't couple with telecine?

I'm playing with matroska container to keep dvd into matroska file 
without recompression.

The procedure is straightforward and pretty simple:
1) getting VOB (a single vob... the usual way ;)
2) demuxing (with VOBEdit for instance) all the m2v and ac3 inside
3) remuxing with matroska (mkvtoolinix V 1.6.0)

Now the problem:

With many movies (not all but quite a few) playing the resulting 
matroska file with mplayer (and also vlc latest versions) on both linux 
and windows the video has evident defects like large squares in small 
(1/2secs) fragments of movie. While playing the VOB it is absolutely 
smooth. Also the video only m2v file resulting from demux plays smoothly.

Interesting fact is that playing the VOB with mplayer with -v -v says 
"telecine" passing through the same fragments. I guess that the dvd is 
filled with hard/soft telecine segments that matroska muxer or container 
cannot couple with.

Did anybody experience same results?

Thanks in advance
