[HELP] Resize doesn't seem to be working

[Selur]

NOTA : isn't it strange that when I open the video with the wrong PAR, we can't see this wrong PAR in the upper-right panel ("base/video") ?

But you do,.. the reported PAR was 1 <> 1:1, it's just not the correct PAR for your source. -> broken/wrong headers

it'd be great to see there that the problem is with that parameter, no ?

Sure,..
The info on the right simply state the detected characteristics of the currently selected audio&video stream.
PAR 1 <> PAR 1:1 so the source isn't flagged as anamorphic which it in your case was.
-> There is no way for Hybrid to know that the PAR or your input is wrong.

I see "stretch = ?" : is it related ? (I don't think so, but..

No. The stretch parameter is there to report the stretch factor that is reported by the container. Only container which supports this atm. is mkv. So if your input isn't mkv or an mkv without a stretch factor the value is a questionmark, which Hybrid will interpret the same way as if the stretch factor is 1.
