[Thomas Schmitt <scdbackup@xxxxxxx>]

Hi,

it is quite sure that you do not suffer from this old bug.
Please file a new bug. Tell what you did with which program,
which drive, which kind of media. Tell what error messages
you get when you try to read the discs.

Please notify me by mail to scdbackup@xxxxxxx about the
new bug report number you got.

Have a nice day :)

Thomas

Bug description:
  SRU Justification
  ~~~~~~~~~~~~~~~~~

  Impact:

    Currently Brasero will fail to write files to a disc in on-the-fly
    mode using the libburnia plugin resulting in 'coastered' media.
    This is the default mode of operation and unless the user is writing
    a pre-built ISO image, this fails 100% of the time and has since Oneiric
    -- possibly Natty.

  Fix:

    Complete/fix part of the following commit:

  http://git.gnome.org/browse/brasero/commit/?id=1b8397ee252df2d554682ca2d694d5937fbf6e39

    Particularly the change to plugins/libburnia/burn-libisofs.c around line
    200 that hoisted the priv->libburn_src->read_xt() call out of the if() statement
    should have actually removed it instead of duplicating it.

  Patch:

  http://git.gnome.org/browse/brasero/commit/?id=253031b69c5dcbcf079c445ec530afb7ccd9ea82

  Test Case:

    * Insert blank CD or DVD in drive:

      (1) Attempt to write files to the writable optical disc by dragging
      files from Nautilus to a blank disc.

      (2) Click on the 'Write Files to Disc' button in nautilus.

      (3) Make sure 'on the fly' mode is enabled by selecting 'Burn image
      directly without saving to disc' (which should be the default).

      (4) Click on the 'burn' button.

    * If the bug is fixed, you should have a properly written and readable
    disc.  Otherwise, the procedure will fail and the disc will be unusable.

  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).
