Okay, I have to agree this might have been true on some firmware revisions in the past, but for (almost) every new firmware I've noticed an improvement on dash media.
When on BSLB or BSOB I never managed to go sub 200k PIE and 1k PIF's. With this release I can see a clear improvement.
MCC-03RG20 (Verbatim branded) at 16x with SB and WOPC on. Burned an old image, (7MB less then full disc). Burntime 10-15 seconds slower then BSLB, but much better quality!
Note also only one "slow-down" when scanning (I can live with that).
Well done BenQ.
