Blu-ray has wrong aspect ration on playback

[Jasonfortheworld]

Howdy! I'm new to the forum, but I'm working on my first menu system. I recently muxed and burned my first test disc and discovered that it plays back at the wrong aspect ratio when put into a Blu-ray player (I tested on a stand alone player and an Xbox One X). Everything (menus and movies) squeezed (not cut off) into a 4:3 frame with pillar boxing on the sides when using a 16:9 TV.

However, the ISO and burned disc all playback just fine when using the PC and a Blu-ray player on a PC. I get the correct ratio of 16:9.

Anyone have any help with this issue or know of a work around?

Thanks a bunch.

Hello,

This usually happens when your video does not meet the Blu-ray specification. Try to re-encode it https://blu-disc.net/features#video_codec.
