"No different from CD tech being brought down in performance during the first several generations of DVD burners. " The problem, though, is this is NOT a BD burner - it’s a BD reader with DVD burner capability. In that respect, there’s no technical reason for it not to be a 16X/40X burner on the DVD/CD side of things. As for the comment about HD vs BD, that isn’t the issue here, but since you bring it up, it’s pretty lame to compare HD’s 1X write performance against BD’s 5X read performance. Not the same thing at all.
