Need to be able to determine/slow down the CD burning speed. This is especially important for ISO files, which generally must be burned to CDs quite slowly.

[Scott Ochiltree]

Binary package hint: brasero

Please see above about the need for a speed option in Braseiro for slowing down the rate at which files are burned to CDs and DVDs. This is especially important for burning ISO images, which generally do not work (boot up) unless they are burned relatively slowly.

Hello there. What makes you think that ISO files require slower burning?

(You might be "blessed" with a crappy CD writer like many people are, which write junk if they're driven to write too fast. However, that has nothing to do with ISOs.)

Hello Sebastian, if you ask something in a bug the right status of it should be Incomplete, you can read more about bug status here: https://wiki.ubuntu.com/Bugs/Status thanks for helping out.

Sebastian:

Thanks for your message. My CD burner is OK, because I was able to use
the CD burning option in Ubuntu (not Braseiro) to slowly burn an ISO
file to a CD. The CD worked fine.

Best Regards, Scott Ochiltree.

do you still get the issue in jaunty?

[Luke Schlather (luke2760)]

It's a general issue with crappy CD writers (and in my experience anything older than 1 year is crappy, and even brand new, stock drives can be lemons.)

If there were a way to make 1/2 the maximum speed the default when burning an ISO, I think that would be good. 1/2 max really might be a good sane default in general, though for raw audio CDs full speed isn't really an issue. If people really want the extra speed they can turn it up, and it would definitely prevent a lot of wasted CDs.

I have this problem with my CD burner on Ubuntu 10.4 and earlier versions.
Under "Burning Speed" only "Maximum Speed" and (for example) "51.9x (CD)" are offered.

With a slow re-writable CD this is not a problem but with write-once CDs it is since they can underrun and burnfree is not always effective with audio CDs.

I am forced to use K3b which *does* offer a full range of speeds and this tends to confirm that there is indeed a bug in Brasero.

I initially used apport-bug to report this which has collected and sent much information but I don't know where it all went!!

I have this trouble too. I'm running Ubuntu 10.10 to burn a dvd+rw and brasero burns it at 4.0x instead of the settings of 2.4x.
Notice that we shouldn't have this trouble have been solved in bug #177124 (but apparently this is not really fixed).
