Comment 8 for bug 1262505

Same problem for me. Maximum speed burns at 1.5x - 2.5x continuously fluctuating up then down. I switched the DVD burner and tried 4 DVDs with the same result. Worse yet, manually choosing write speed gives me the options of 4x, 2 identical options of 8x, and 2 identical options of 16x. I randomly chose one of the 8x options and again, same slow result.

K3b burned an entire DVD in a little over 5 minutes, achieving 16x which it auto selected, which means the troubleshooting aims straight at Brasero.

Brasero was great before, but something changed. ISO images appear to burn normally, at least my last image burn was okay about a month ago. But making a data DVD was terribly slow.

Info:
Ubuntu 14.04 LTS
DVD disk type: Kodak DVD-R (Ksb burn it with no problems)
Burners:
1) Hitachi/LG GSA-H60N 16x DVD±RW DL SATA Drive
2) Hitachi-LG GH10N SATA 16X Multi Recorder DVD+R DL DVD-RW Drive LGE-DMGH12L(B)
Attempted to create data DVD with .avi and .mp4 video files
