Benq DW1620Pro slow at PI scan

Hi, just got my DW1620Pro today together with some DVD+R discs. I tried do do a PI scan, but it is really slow. I have tried with both Nero and DVDInfoPro.

I selected 4x speed, but the speed stays around 1x. Is this normal? My firmware is VB7S9.

Er, never mind. I downloaded a newer version of CDSpeed and it’s ok now!
