Bug Description

Binary package hint: brasero

I launch Brasero in order to create a data disc with a DVD+RW on my Dell 1525 N laptop (which is fully linux compatible).
The burn process work correctly and Brasero advise me at the end that everything is OK, and the disc is ejected.
Then if I try to insert it again in my driver, the DVD reader turn for some time but no windows open in order to allow me to select any action( eg: open in Nautilus). Also the DVD is not mounted and I do not see its on the desktop or in Nautilus.

I got the following message when running dmesg | tail
[ 150.052063] iwl3945 0000:0b:00.0: Failed to get channel info for channel 120 [0]

I made 3 tests with 3 differents empty DVDs and the result is always the same. I have recorded a log of the third test which I attach to the bug.

Reading more carefully bug report I have seen this one https://bugs.launchpad.net/ubuntu/+source/brasero/+bug/780117 which explains that:
"
This problem only exists when burning On-The-Fly. Burning ISO Images or automatic creation of ISO Images before burning works without problems.
"
This is the point! I try to first create an image and then burn it to the DVD and it works as expected. The there is really a software issue with direct burning of DVD.

Changed in brasero (Ubuntu):

I've been bitten by this problem too: I burned a data DVD with Brasero, only to find (a few weeks later) that I cannot read it.

Brasero's behaviour (exiting successfully while the DVD is utterly useless) is quite... unfortunate. I can't start to check up after all programs when they told me everything is fine whether that *really* is the case (!!).

As you can tell, I'm rather angry since it seems I'll be losing data that's important to me due to this bug.

I don't know much about the business of writing DVDs/CDs, so I would really appreciate any and all pointers on how I might go about salvaging some of the discs contents. Thanks!

I hate Brasero; it consistently screws me. I gave it one more chance last night and it screwed me again. The program inexplicably crashes SOMETIMES when I attempt to remove a file from the project, and when I burned my data DVD it made it all the way to the end, did the "unable to eject disc" error, then delivered me a nice shiny coaster. Bollocks to that.

I'm with the others suggesting K3B. Can we make THAT the default package for future Ubuntu versions?
