I don't recall what mine were like originally, but I reflashed both of my Pioneer DVD±RW drives to remove region locks and the godforsaken RipLock feature.
For those who aren't aware, certain drives have a feature enabled in firmware to run the drive slower when DVD-Video disks are in the drive so they don't run super super loud when watching a movie. This also dramatically slows down rip speeds when using Mac The Ripper or Handbrake. Reflashing the drives can remove this, as long as you're willing to deal with more noise. Personally, I keep my machine under my desk and out of the way, so I don't give a damn about the noise.
