I have some dvd-master dvd-r disks that have generatrion 4 written on the packaging.

However, when I check them in DVD decrypter (mode, iso, write) it displays Ritek GO3.

Does GO3 mean generation 3?

I have queried this from whom I got the disks from and they GO3 means generation 4.

Shouldn't it then say GO4?

Can anyone advise?

Thanks
