XBox One: 720 x 576 being rendered narrower (4:3 rather than 16:9)

[oceanclub 4]

I have a TV programme encoded as 720 x 576. (Codec details at bottom). When I play this on my PC, either using Emby on the desktop, or using a video player such as VLC, it looks fine. However, when I play it on Emby on the Xbox One, the aspect ratio is more narrow and visibly obvious (elongated people). Anyone know a fix?

Regards

Paul

The Display Aspect ratio is shown as 16:9, so Emby is behaving as expected other than on the X-box.  Maybe the file contains display dimensions or PAR (pixel aspect ratio) values which contradict that and the X-box is going with that data.  Is that data from Emby? Using MediaInfo might show something to confirm my hypothesis.

I expect the fix is to use MKVToolNix to change the Display Dimensions or PAR in the header of the file - or even just removing the contradictory information completely.

Thanks - in MKVToolNix I noticed Video Properties > Display Width/Height was set to something like 1080 x 578 - I tried deleted that and also specifying 720 x 576. Neither worked; in the end I just extracted the MKV, reencoded the video and put it back in. Works now.
