[Matroska-users] Cannot Extract Tracks (Garbled Output)

Hi everyone. I'm new to Matroska, but it looks like a very interesting

I have a few clips here that I cannot seem to extract using
mkvextract. Doing a `mkvmerge -i` on the file shows the following

Track ID 1: video (V_MPEG4/ISO/AVC)
Track ID 2: audio (A_AC3)

However, when I try to extract it, the output is all garbled blocks of
colors and mplayer gives these errors: 

AC EOB marker is absent pos=66
AC EOB marker is absent pos=66
AC EOB marker is absent pos=92

I tried a few variations, but the command I've tried for both clips so
far is this. It goes fine without any errors, but the output of both
the avi and ac3 is all garbled.

mkvextract tracks file.mkv 1:test.avi 2:test.ac3

Sorry if this is a common question, but I did search the FAQ and lists
but didn't come up with anything.


Thanks in advance!
