Here are scans of 5 discs I burned with my BenQ drive as a Plextor 740A v. 1.01
One thing to note is that Plextor's version of WOPC is always on and can't be deactivated. I was also unable to verify that autostrategy was either on or off - I don't think it is supported in this firmware yet as the speed scans looked virtually identical to the BenQ with WOPC on. I created data discs using Nero CD/DVD Speed. However, as a Plextor the drive does not support Disc Quality check, so the scans were created using the BenQ1640 with BSIB.
Overall, I had no issues with my drive as a Plextor and the burns went very smoothly.
