Wrong Aspect-Ratio with SD-Format

Hello,

I use Avidemux (x64 2.6 latest version on Win10 with LAV decoder) in order to quickly cut (no re-encode) DVB TV-recordings (TS-files, SD in MPEG2 and HD in h.264).

Nowadays most of the material is in 16:9 aspect ratio, but Avidemux opens SD-resolution always as 4:3 preview, even though file/Information (and Mediainfo) shows the aspect-ratio as "PAL  16:9 (64:45)".
But not only the preview is wrong, the saved file is also in the false 4:3 aspect-ratio if I don't force the correct display width (1024) in the muxer.
There is no problem with h.264 16:9 files, only SD resolution is affected.

Is this a bug in Avidemux?

Thanks for help and best regards!

Avidemux displays 1:1.
This is inherent for SD video. This could be either 4:3 or 16:9. Force display is way to go.
