GNOME Bugzilla – Bug 542676
Provide a very slow speed rate in drive properties
Last modified: 2008-08-14 16:05:13 UTC
Provide a fallback slow speed rate (2X) if there isn't one already in drive properties. Some audio cd reader have difficulties with discs burnt at high rates, and with modern burners you get only relatively high rates. Actually i got from 56,4X to 9,6X with cdrdao plugin.
Created attachment 114441 [details] [review] provide a slow rate of 2X if it's not alread available Diffed against latest svn, apply with -p0.
Thanks for your patch and report and really sorry for the delay. Sorry also but your pach is not valid. I think your bug report is more about #537871. There was (hopefully that's no more true) a bug where with some drives brasero didn't report all speeds available and moreover didn't use the right factor to compute speeds from the rates returned by the drive. Now 2x speed is not always possible, when burning you must stick to the available rates (those returned by the drive) which are a mix of the medium possibilities and the drive possibilities. For example my drive with a 10x CDRW can only burn this medium at 10x. No other speed is possible. A simple test is using wodim or cdrecord with cdrecord -dev=/path speed=2, I'll then see a burning at 10 nevertheless because that's the only possible speed. I used to think like you that is all speeds were possible under maximum speed but I learnt otherwise. That's why your patch cannot be commited. Thanks again

I've checked latest svn and now i have speeds from 48x to 8x for cd-r, which i believe is the Kib -> KB conversion fix. > Now 2x speed is not always possible, when burning you must stick to the > available rates (those returned by the drive) which are a mix of the medium > possibilities and the drive possibilities.

But with cd-r lower speed should work, i've been able to burn cd-r at 4x with gnomebaker on the same machine and the same wodim version. So from my own experience while not advertised lower speed should work with cd-r. Said that, i understand that my patch is not ok for inclusion and needs improvement. I'll try to do so and maybe repost to have you changing opinion on this ;) thanks
