Also please look at Thomas’ comment. The patch is just for some follow up comments in this report. The original reporter of this issue (LP:780117) has a different issue with growisofs. Though closing this report might be wise and people still experiencing problems with Brasero should submit new reports as this report here is way to confusing with all the comments.

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: Revert part of the following commit: http://git.gnome.org/browse/brasero/commit/?id=1b8397ee252df2d554682ca2d694d5937fbf6e39 Particularly the chage to plugins/libburnia/burn-libisofs.c around line 200 that adds an additional priv->libburn_src->read_xt() call. 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).
