Gaming [QUESTION] Repointing ISOs?

[Raiser]

So I have DJ Max Black Square.
I want to delete the opening video at the beginning, but how do I repoint it?
I read somewhere that you need to do some sort of repointing or something.

You can relink the video file in the iso to another video file that is in the iso that is shorter. Or you can dummy the file. If you dummy a file, it is replaced with a 0kb file with the same name. This will make the opening movie not play anymore because the data for the movie is deleted but a placeholder for the file is still there. Or you can just delete the movie file and repack the iso. Use UMDGen v4.
