Is it ok to use it in my Slim V12 Ps2?

I got these Arita G04 disks and was having troble buring them at 4X the speed since they keep fail one after another.

When i try to write the Disk at 2X the speed the buring process finished with out any errors. Is it save to them in my slim V12 Ps2?

thanks

I would go buy some taiyo yuden or ritek.

maybe update your burner's firmware??

The Arita G04's are supposedly a lower quality Ritek G04. The quality of burns may depend on your burner. So as flimflap suggested, check to see if you have the latest firmware for your burner.
