OK, I will change for this.
But : what should I write for "MPEG Audio 2.5 (some MP3 have this, extended version of MPEG-2 Audio...)? MPEG-2.5 Audio?
but : "MPEG-1 Systems Multiplex" is long . I think I will change it in MPEG-x PS, and MPEG-x TS (see below for TS)

if you know MPEG system, could you tel me where PS is used (DVD, and?), and where TS is used?
I have difficulties to understand all in the MPEG standarts, they are a little difficult with a lot of standarts

OK, I understand more what you said.
And as you said, Video ES or Audio ES (=MP3 or raw AAC) doesn't have a container, so I use the ES name in place of the container name, and I think to not change this.

Thank you for your analysis.
