reports 0% until finished, also slowly burning at speed 0.3x or 0.5x

Note: this bug may be related to bug 371002.

I confirm this bug on jauntu 64 bits

Thanks for the report, could be similar to bug 277977. May someone having the issue send this upstream at bugzilla.gnome.org? For forwarding instructions please have a look to https://wiki.ubuntu.com/Bugs/Upstream/GNOME ; Thanks in advance.

I sent it upstream here: http://bugzilla.gnome.org/show_bug.cgi?id=582261

here is another screenshot

Thanks you for sent it upstream!.

For what it's worth:

I originally reported this based on my experiences on my 6-year-old desktop computer, using an LG DVD burner (I can look up the actual model when I get home).

Today I burned my first DVD using my laptop, a Lenovo T61 which uses a Matshita drive, and the exact same thing happened.

Please forward any comments to the gnome bug:

The bug has been marked as fixed at gnome: http://bugzilla.gnome.org/show_bug.cgi?id=582261

It's nice that it's fixed at Gnome. Will we get an updated package in Ubuntu 9.04 or not?

As you can see at the bug status, I have nominated it for Jaunty and Karmic, we will see what the ubuntu folks say about it. :)

And where is the fix?

> And where is the fix?

It said "Changed in: brasero", not "Changed in: brasero (Ubuntu)", the
fix for Ubuntu is not applied yet.

As it is stated there the problem seems to be the plugin used.
I also had this problem, as it was using wodim to burn the iso instead of growisofs.
To remove wodim is not possible in a clean way as Brasero is marked to depend on it and it will be removed along with wodim.

But there is a quick and simple workaround to fix half of this problem.
Using Gnome Configuration Editor navigate too:

apps > brasero > config > priority

In there it list all the plugins found and their priority, by default all are in 0 so Brasero chooses the one that fit the best.

Two things can be done here either disable the plugin in this case wodim and that is done by changing the value to '-1' or
to increase the priority of the one we want and i went for growisofs and in that case giving it a value higher than 0.

In my case I did both:

growisofs-burn = 1 (raises the priority forcing it to be choose)
wodim-burn = -1 (disables it)

This fixed my problem regarding the wrong percentage been showed as soon as it reaches the 2GB mark as for the burning speed is still slow even while using growisofs.

Thanks for the partial fix Nandox7. As for the slow burning speed, I noticed that when I choose the burning speed manually, in my case 8x instead of the "max" value, the burning is performed faster.

What is correct file path from within Xubuntu Jaunty?

The correct path would be:

~/.gconf/apps/brasero/config/priority/%gconf.xml

Edit the file with values mentioned above. To me, Brasero using wodim burns unreadable DVDs (wodim 9:1.1.9-1ubuntu1 64-bit).

I kept doing some other tests with this, specially regarding the speed.
And the speed problem doesn't seem to be from Brasero but from growisofs or wodim.
Easily tested by calling growisofs directly, there is no change in the speed.

Some external links refer a problem with how the buffer works and how it detects the available memory, but supposedly a fix for that was released not long ago. Still, even passing params to define a size for the buffer had little impact, i noticed a slight increase in speed.

Also i noticed a interesting report where someone stated that it might be using wrongly the burn-proof feature of the burners ending in poor quality burns and slowing down the process. Unfortunately all my DVD burners have burn-proof so it was impossible to try out with one without.
On the other hand I don't see growisofs outputting anything related to that, so I'm not sure if this can be a problem.

1. Try burning at lower speeds (e.g. 2x or 4x)
2. Try with a different dvd burner (I mean your device/hardware, not
the software).

I tried with a DVD-rewritable disc (4.0x maximum speed):
- burning 1.6GB image
- burning 4.3GB image
- burning 3.3GB of data

All successful!

Ah wait, the problematic plugin is *wodim*. You should be using
*growisofs* instead of wodim.
Change the priority, it was mentioned earlier. :)

Thanks.

The workaround solves the problem in a dirty way. It will be better to release a fixed version of Brasero via Ubuntu Update.

I agree, that fix means Brasio no longer supports my CDRW discs. Have reverted to normal priority & wodim.

The upstream bug was fixed in 2.27.4

There only appears to be 2.26.1 in Xubuntu repository?
