My Edited DVD is not Playing properly after burning it

[MewtwoFanz]

I'm new here, and I'm trying to add subtitles to an official DVD ISO and burn it for personal use.

I'm using method 2 from this tutorial to do so: https://forum.videohelp.com/threads/277950-How-to-add-new-subtitles-to-an-existing-DVD

However, when i burn it with ImgBurn or any other ISO Burning software, the menu is all black and unusable, and the audio stutters.

I tried to remake the iso file, i tried burning it with a different program, and nothing changes.

Can anyone help me?

Do not concentrate on the ISO so much – it first needs to play fine from the VIDEO_TS folder in software on the PC before you go ahead and burn it.

The way you did it we cannot make out whether the issue is burning/media related or if it is due to your modification of adding a subtitle track.

I checked the VIDEO_TS Folder too. Everything seemed to work ok.

How exactly did you check it?
