Dummy Files in this day and age?

[Cyber Akuma]

I was scanning a very recent 4 cd game woth CLONEY XXL, and CDs 2 and 3 were listed as having Dummy File protection. I read the FAQ at Cd Media world but it said that basically this can be overcome with a 80 minute CDR. I dont understand why somebody would use something like that in a new game since I havent even seen a 74 min blank cd for sale for years. Is there some other Dummy File trick companies use now as cd protections?

Mainly I want to know how to burn a working backup, the fact that I can bypass the cd protection if I just use a 80 min cd on a new and popular game released by a very wealthy company seems too good to be true.
