Maybe I have to use Windows to get a decent video editor :-/ you will have the same problems.
some notes:
* your file is very large. Can you record some example of 5 or 10 s and post them somewhere for we to try?
Well, I would have to do it with dd for reliability. No tool I know so far can copy video and audio (two tracks) cutting a region without crashing or manipulating the tracks. I can not tell the recorder to start and stop at points of my choosing. I have to tell it to record certain program, and it chooses the points from the official start and end times of the program. If I stop the recording, it deletes the file.
* I can't verify right now, but I'm reasonably sure ffmpeg can extract all video and audio from ant file
Yes, it can, but it does manipulation of the original so that may you would not see the problems I see.
* I think (only?) mkv can have several audio tracks
No, avi can as well. What is not typical is to include subtitles on avi, but it is on mkv.
When demuxing, all the tracks have the very same lengh (about time, not size, of course), so they can be worked on easily
it may be easier, then, to move them to mp4, for example, before editing to have the smaller file possible, because, of course, you can't edit the tracks separately :-(
No tool I know can do it. If I tell ffmpg to convert the entire stream to something, there are losses. If then use another editor to remove sections, there are more losses. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
