Pioneer DVD-117 firmware without riplock

I am using the latest firmware (v1.07 RPC-1)

During speed testing the drive appears to be rip-locked

I tested with a clean dvd5 pressed disk

using Nero dvd speed

starts 6.49X
ends 15.31X
total time 4min57

I think the drive is read speed limited on dvd-r disks (datasafe ritek G04 grade A), because it starts at around 2.5X and ends at 6X.

Could someone have a look at the pioneer firmware please?
