SH-182D only burn Verbatim DVD+R DL at 2.4x?

Strange, as I recall this drive can support 8X DVD+R DL, and these Verbatim +DL disc clearly state 8X capable.

Only option when insert these disc is 2.4x…

My firmware is SB04.

They’re only 8x capable if the drive will overspeed them. They’re really 2.4x discs (MKM A01), and your drive burns them at their rated speed. You’ll need the actual 8x Verbatim DVD+R DL discs (MKM A03) to burn at 8x.


Any way to tell which media code from package?

2.4x rated is always MKM001, 8x rated is always MKM003.
