Program to add an audio track to a mkv file?

[supercain]

Hi,

i want to add an additional audio track to a 4GB mkv movie. I use virtualdubmod but it crashes as trying to open the file. Is it because its too big for it to handle ? is there any other alternative out there for such a task? i have avidemux too but i cant set a name for the track there (such as English, Spanish, etc.) so i would require a better program. Also, since im not editing the video or the audio at all, something with a direct stream copy option would be nice.

Thank you.

mkvmergegui.

But this is not authoring a blu-ray. Moving you to our video conversion section.

Thanks for the hint. Seems like a very useful program. Just one question. I didnt find in the settings anything about direct stream copy. Is this the default setting?

Thank you.

Yes, it copies everything. It can't do any reconversion.
