Good to know.

That also fails:

The above ends with no file being created. There are indeed also subtitles, but I don't want to keep any.
And here the version without mapping, the one that again (this time creating a mkv, not an mpg, and not using stream-copy as well) results in just video without any audio. (I leave out the banner, it is the very same than above.)
