muxer information missing in Media Information, despite explicitly stating it should be shown

[teo1978]

Steps to reproduce:

1. Open a video file
2. Go to Tools / Media Information
3. Go to the "Codec" tab

Expected:
information about the muxer should be shown somewhere. If not in the "Codec" tab, then in some other tab, in which case the description of the Codec tab shouldn't falsely claim that muxer information is displayed.

Observed:
At the very top of the tab it says:
(and no words can express the hatred I'm feeling because of the fact I can't copy and paste that text but have to read and type it):
"Information about what your media stream is made of.
**MUXER**, Audio and Video Codecs, Subtitles are shown"
(emphasys added)

Yet, there is information about the video and audio codecs, but nothing about the muxer.
