Let me read this for you

https://www.howtoforge.com/creating-your-own-distributable-ubuntu-dvd-relinux

"The image created with Relinux can under no circumstances be greater
than 4 GB, which is why you will need to exclude the home folder as
well as possible other folders too big to include."

"If you do not exclude enough files to bring the squashed file system
to a maximum of 4 GB, Relinux will not create an image out of it."
 
"Make sure that the content you want on your DVD does not exceed the
size of 4GB!"

Let alone https://en.wikipedia.org/wiki/ISO_9660 and the max. size of a
single DVD, even if you want to burn data by several small files.
