How can I downspeed LiteOn/JLMS XJ-HD166S?

I have JLMS XJ-HD166S with stock FW DS1E for KProbe disc quality scans of my birned DVDs. And I got a little trouble - scans made with my JLMS - at 8x, but standart must be 4x. How can I downspeed LiteOn/JLMS XJ-HD166S for scans at 4x. KProbe can’t downspeed my device… :sad: Help me, plz.

Oh,thank you dicer! :bow: CD Bremse can manipulate speed of my device! :iagree: KProbe works fine & my scans looks much better!

I like scanning my disks at 8x on my Liteon 166S drive.

It gives a reasonable view of the burn performance under reasonable stress, instead of the ultra-perfect scans given by running the scanner at slower speeds. That way, poorly burn areas that scan fine under slowers speeds are highlighted.
