Yep, with my 109!! Can't believe how good of a DL @ 4x & 6x, as well as 16x on Verbatim burns I'm getting here (see my ::Good & Bad Media for 109/A09 :: thread)! It's even better than what I'm getting off the LiteOn 1633S or my Plextor 716A!
It's not to say the 109 is the 'best' for all uses -- here, the Plextor 716A is quieter at tray open/close, and has Plextools for PI/PO scanning (offical product, not a 3rd party thing like CDSpeed/DVDInfoPro/etc).
But if you really want the very best PI/PO error charts on 6x DL burns, the 109 is it! I certainly have not seen any other drive (LiteOn, Sony, NEC, Plextor) do any better! And, the PI/PO error rates are so low on the 16x Verbatim burn, it's astounding! (total less than 6500 PI errors!).
