DVR 106 burn speeds

I have a dvr-106, but I can’t get the thing to burn any faster than 1x. It’s got the 1.07 firmware, which came installed on it, and I’m using nero 6.3

Nero knows that the drive is 4x speed, or 2.4 for rw drives. When I burn, it offers the appropriate options for speed. Yet when it starts burning, it declares that it is burning at the appropriate speed. But it plainly isn’t!

Any clues?

  1. enable DMA on all drives
  2. change media

You sir are a star!
