Burning dual layered

i have nero 6.6.0.1.4 and i want to burn dual layered. I trie to burn but the program cannot detect the disc info. The dvd drive is a dual layered sony DRX-810UL, do i need a better version, because it came with the dvd so i was assuming it could burn dual layered. ANy help??? thanks

What for a DL disc you’re usin?

double layered DVD+R memorex recordable

Your drive is a rebadged benq drive, maybe a firmware upgrade would help, also could you post the mediacode of this DL using dvdidentifier or Nero cdspeed. And i’d recommend to use for DL backups only Verbatim media.
