I haven't used Vegas for quite a while because of old age. I imported an older DVD video that I made in scope, split part of it off then changed the aspect ratio of one of the parts to 1.85 x 1 then rendered both parts to Bluray disc in a Windows 11 computer with "M" drive using Vegas to write the disc. It all worked flawlessly. I was absolutely stunned. Something worked that I didn't have to hit with a hammer to get it to work properly.
