I have a box of Verbatim DVD+R DL that are labeled "2.4x = up to 6x with compatible high speed DVD_R DL drives). Anyway, my DW1640 (firmware = BSRB).
I burnt an ISO that is 7,133,100 KB in 18 min (1,080 sec). If 8x = 11,080 KB/s then 1x = 1,385 KB/s, right? So my drive did it @ 7133100/1080 = 6,604 KB/s and normalizing to the “whateverx speed scale” should be: 6,604 / 1,385 = 4.8x
Why can’t I burn @ 6x with this drive/media?

I have SATA HDs so it’s not because the HD is slow.
