[solved] editing MKV without remuxing

Hi. Do you know a tool which allows me to edit MKV metadata/headerinfo(?) without remuxing the whole file?

E.g. renaming one or more audiotracks and setting the correct language codes in an 8GB mkv file.

I think I had seen such a tool in the tools section but I checked back there and I just can't find it. I searched for mkv and read the description of all of the 90+ search results, but couldn't find the tool.

Many thanks for any help.

mkvpropedit. command line tool included in mkvtoolnix.

Thank you.
While I like command line tools in general, it seems quite a bit complicated for this task.
Would you know a GUI tool, too?

There is also the header editor gui in MKVtoolNix. It can be found by accessing MMG, the gui for toolNix. It is one of the options avail if you access the file drop down options. While it does not do that much editing it does do some things and no re-muxing of the origional file is needed.

thanks so much, both of you.
