Bug description:
  Binary package hint: brasero

  When I burn a DVD (4,7 and 8,5 GB) Brasero show the progressbar till
  about 30-40% (exact point is randomly) and than says, that it is
  finalizing the media. This finalizing messages is showing for the rest
  of the burning process (~10min @8x 8,5GB). After that, it ejects the
  media without any error. But when I insert the media again, nothing
  happens, except, that the DVD-Drive disappears from the "computer:///"
  location in nautilus.

  This problem only exists when burning On-The-Fly. Burning ISO Images
  or automatic creation of ISO Images before burning works without
  problems. The burning speed doesn't matter to this problem. I test 8x,
  4x and 2x. All the same problem. On-The-Fly burning using K3B works
  quite well @8x speed.

  One thing I also notice is, that Brasero uses 100% CPU on one core,
  while K3B uses just about 5-15%.

  I attached the last Brasero log. I don't know, why it just says, that
  it was only at 49% and then says it's finished. The burning took about
  28 minutes. The media was unusable on all my three devices
  (Linux/Windows).
