Hi there,

i read some articles and tutorials on this nice site, and found out, that there is tools that let me demux MKV-Files under MacOS 10.5 (Leopard). So i downloaded 'mkvtoolnix' to do the job and start with extracting the tracks so i can remux/re-encode them later on.

Now my Question:

The MKV-Files i want to demux (which are in fact TV rips of a TV show i want to archive to DVD) contain 2 Tracks. One Track is a H264/AVC Videostream, the other is the AC3-Sound. Once i play the MKV-File in VLC, everything works/plays fine. But when i extract the H264/AVC Stream using mkvextract (contained in the mktoolnix suite) using the command

Code:
mkvextract tracks mymkvfile.mkv 1:video.h264 2:audio.ac3
i am abled to play the AC3-Stream in VLC, but the H264/AVC Stream plays crippled/stop motion like.

Strangely enough that does not happen if i have a combination of MKVFile with MPEG4/AC3 tracks...

What am i doing wrong? Why does the replay of the MKV-File work in VLC before demuxing, and why can't i play the extracted H264/AVC stream after extracting.

Any hints? Thanks for your help in advance!
