Problem reading new burned games

[InspectahM]

hello all.
Last week I update my TS-H943 Samsung ms28 drive to the last firmware.
Now if I try to run recent games(COD MW2, Forza, Assasins Creed ...) very often I get the message "Unauthorized disc" then press ok and the console restart.
I already try to play some original games and it's all ok.
I have two drives(my first had a laser problem and I bought a second one,then I repair it) and it happen the same on both drives.
They have the same firmware version.
Could it be some firmware ichue?
Could it be the burning method?(I'm using Img Burn with auto-calculate layer break
My media is a dual layer Verbatin.
Does anyone have the same problem?

Are you burning with BurneMax firmware? Truncated burns don't work.

Well no.So I need a special burner and flash the BurneMax firmware on him right ?

yep. you need an ihas drive version b. flashing them is quite easy but u can buy them preflashed. ebay is loaded with them. as long as its version b your set, dont put much thought into the rest. once you have it look into checking your backups with kprobe if your playing on live. they do have to be broken in so to speak... but theres countles forums on that subject.
