8x ePro discs but 2.4x in Nero

Hey guys!
I buy ePro (eproformance) DVD+R 4.7gb discs for my needs and i’ve never had a problem with them.
I’ve been buying 8x discs but they only burn at 2.4 in nero. to be honest i haven’t tried another software yet, but i tried other brands and they do burn at 8x.
According to DVDInfoPro:

Media code/Manufacturer ID PRODISC R03
Manufacturer Rated Speed 8.0x 11080KBps
Available Write Descriptor CLV 2.4x 3324KBps

So…why the heck nero can’t burn at higher speed? It did before…

Speed is set by the drive, not the software. Update your drive’s firmware and it could help, but if you’re using an older 4x drive you are outa luck.

but my drive is 8x…and other media it burns as 8x as normal

Doesn’t matter, each media type is different, and speed is set by firmware. Update your firmware, you can get it from the drive’s maker.
