Brasero burns DVD-R very slow

[Andrej Mernik]

Binary package hint: brasero

Brasero in Lucid Lynx burns very slow. The DVD is Optiarc AD-7191S SATA drive and supports 16x writing. The inserted medium is Verbatim DVD-R that also supports 16x speed. The data is written only at 2.5/2.6x speed average, sometimes it also jumps between 3.0x and 2.0x. The data is correctly written (verified with md5 sums).

My other specs are Dual Core Athlon X2 4850e, 2 GB RAM and 160GB sata HDD.

Thanks for your report, could you get a brasero log? please run brasero as: brasero --brasero-burn-debug --brasero-media-debug &> brasero-debug.txt ; perform the operation to reproduce the bug and attach that resulting log file to the report, thanks.

Hi, here is the log. I cut out the file names and removed output from md5sum generation at the end, because it was only bloat.

I am getting this also, both in Mint 9 and Mint 10 (Lucid & Maverick), had no problem with Karmic, there are a lot of people complaining about this bug on various forums, would be nice to have a burner that actually works reliably without having always drag all the KDE dependancies into Gnome just to get K3B which does actually work properly.

I notice this bug is LOW priority, if you're going to develop a pogram why not do it properly or if not then just bin the project so that users don't have to keep losing money by throwing away blank media.

Just thought I'd add that Natty (11.04) *STILL* has this stupid bug. Tried to burn a DVD with it, said it was going to take 30+ minutes at approx 3mb/sec (fluctuating). At first I thought, maybe my DVD burner is crap, or packing it in. Loaded K3B, was able to burn a DVD at 15-20mb/sec with no problems.

Seeming as this bug hasn't been fixed in well over a year, and brasero is just a pile of junk which nobody seems to actually maintain. I think it should be removed from the next version of Ubuntu. Its embarassing.

Report that it still happens with 12.04.

Burn speed starts off at 3.<something>, then rapidly drops to 0.8x.
