Wrong aspect ratio for recorded IPTV stream

Description
When I play a recorded file in VLC or XBMC, I got a 4/3 aspect ratio for a 1080p stream.
File is attached.
It is rather a 1/1 aspect ratio:
+ Display unit: 3
+ Display width: 1
+ Display height: 1
This is what is specified in the ITU-T H264 document:
aspect_ratio_idc specifies the value of the sample aspect ratio of the luma samples.
Table E-1 – Meaning of sample aspect ratio indicator
aspect_ratio_idc Sample aspect ratio (informative)Examples of use
0 Unspecified
1 1:1 ("square") 1280x720 16:9 frame without horizontal overscan
1920x1080 16:9 frame without horizontal overscan (cropped from 1920x1088)
640x480 4:3 frame without horizontal overscan
So I don't think we can copy this into the mkv (according to me, it is not the display aspect ratio)
- Found in version set to fixed
