I recently came accross an AC3 track of a tvshow I already had on my system. The file has an "ac3" extension.
I felt lucky so I just placed it in the same folder and gave it the same name as the avi.
I was hoping I could choose another audio-track while playing it, but alas...

Is this possible in another way without merging/packaging them?
Could this be a nice feature suggestion?

How easy is it to merge 2 of those files to 1?
Is it possible with matroska if the file is in sync?
Can I define some kind of offset if the file is timeshifted?

I installed the mkvtools on my NAS. It 'forgot' to install lzo on which it depends but after installing that I was able to do this:

Code:

# mkvmerge -o Defying.Gravity.S01E01.mkv -A Defying.Gravity.S01E01.avi Defying.Gravity.S01E01.ac3
mkvmerge v2.9.8 ('C'est le bon') built on Aug 14 2009 05:05:17
'Defying.Gravity.S01E01.avi': Using the AVI demultiplexer. Opening file. This may take some time depending on the file's size.
'Defying.Gravity.S01E01.ac3': Using the AC3 demultiplexer.
'Defying.Gravity.S01E01.avi' track 0: Using the MPEG-4 part 2 video output module.
'Defying.Gravity.S01E01.ac3' track 0: Using the AC3 output module.
The file 'Defying.Gravity.S01E01.mkv' has been opened for writing.
Progress: 100%
The cue entries (the index) are being written...
Muxing took 89 seconds.

All this on a poor 128 MB / Mips device (WD Worldbook 1 TB)

I still have 2 second timeshift. Is there something with which I can easily control the cue entries? Well, this is getting a bit off topic now.
I will also search for a program with which I can just cut the 2 leading seconds of the AC3-track...
