I need help from someone experienced with the CentOS bug tracking
system. I gotta say it is one of the most complicated and imposing
front ends I've ever seen. Could anyone familiar with it please file a
bug on my behalf? Particulars:

"CentOS 7.9.2009 DVD iso image too large"

ISO image: CentOS-7-x86_64-DVD-2009.iso 4.7GB raw CD image
Wed Nov  4 05:37:25 2020
Burners: Both K3B and Brasero
Media: Both DVD-R and DVD+R single-layer disks

iso image: 4,712,300,544 bytes
User Anthony F McInerney advises Wikipedia says
DVD-R capacity: 4,707,319,808 bytes (max)

I have tried burning this same iso image on two different machines: a
CentOS 7.9 server and a Fedora 33 laptop. Same failure on both.

We need to ask the developers to make a re-spin that's about 5MB
smaller. And before someone suggests it, the 2010-vintage server I'm
trying to install CentOS on does not support booting from a thumb
drive, so that option is not available.
