Hi, for completeness: One of the two Debian patches replaces the theory of SAO-versus-TAO. It turned out that the function, which transmits the libisofs image data to the burn software, dropped every second data block. (Actually the first block of each pair of blocks.) https://bugzilla.gnome.org/attachment.cgi?id=226272 The bug was obviously introduced two years ago by changes which are announced at: https://bugzilla.gnome.org/show_bug.cgi?id=630651#c12
This explains many of the follow-ups here. But not the original report where libisofs and growisofs ended after only half of the work was done. Have a nice day :) Thomas ** Bug watch added: GNOME Bug Tracker #630651 https://bugzilla.gnome.org/show_bug.cgi?id=630651 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to brasero in Ubuntu. https://bugs.launchpad.net/bugs/780117 Title: Brasero finishes without error but unusable media [on-the-fly mode] (Ubuntu 11.04 ->12.04) Status in A disc burning application for gnome 2: New Status in OEM Priority Project: In Progress Status in OEM Priority Project precise series: In Progress Status in “brasero” package in Ubuntu: In Progress Status in Baltix GNU/Linux: In Progress Status in “brasero” package in Fedora: New 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).
