I've tried;
1 ) I've tried remuxxing through MKVToolNix GUI first by setting the correct display width, and then editing the headers, following this post with no luck (despite showing in MKVToolNix as 1024x576, the domensions still read at 720x576 in anything else. The attached window grabs are all the same file) https://www.makemkv.com/forum/viewtopic ... =7&t=20505

2) I've also tried using gMKVExtractGUI and Restream according to this post; https://www.makemkv.com/forum/viewtopic.php?t=8499. Note; the post uses MKVExtractGUI which no longer works, so I used gMKVExtractGUI.
3) I tried doing a similar thing using DVDpatcher, as per this post. https://www.makemkv.com/forum/viewtopic.php?t=5086
For both of these I end up with a strange green artefact - it seems to have added this onto the edge of the 'squashed' 720 image

The MKV will play at the correct ratio in VLC, but I want to be able to open the files in some video editing freeware (OpenShot) and this is where it's causing problems as I have to use an odd profile to get it to play whilst looking at the correct ratio, but it will not export without looking squashed. I've tried alternatives to OpenShot such as VSDC (which can display and export at the correct ratio, but even the highest quality makes it blurry), but I'm yet to find something that doesn't either alter the quality or add watermarks. I'm hoping to be able to solve the problem at this end, rather than trying to handle it during editing.
