Problems reading MKM 01RW6X01 with 1620

Hi! I have BenQ DW1620 B7V9 speedpatched.
I’ve bought one MKM 01RW6X01 (Verbatim DVD-RW 6x) for testing.
I’ve burned it at 4X with DW1620 & DVD Decrypter, it finished successfully.
The disc is perfectly readable at my H&B DX-3255 standalone, but it is not readable in the DW1620. Anyone has the same problem?

DW1620 recognizes the type of the DVD, reads the label and then it reads nothing more. Nero DVD speed test says “No additional sense information”.
