This appears to have been a media issue. I have now gone through with dvd+rw-mediainfo to check the media speed, as well as having the drive speed. Some of my supposed-to-be-faster media reports a alower speed, as viewable with dvd+rw-mediainfo.
I am currently burning with media that reports the following: $ dvd+rw-mediainfo /dev/dvd INQUIRY: [MATSHITA][DVD-RAM UJ-852 ][RB02] GET [CURRENT] CONFIGURATION: Mounted Media: 1Ah, DVD+RW Current Write Speed: 4.0x1385=5540KB/s Write Speed #0: 4.0x1385=5540KB/s Write Speed #1: 2.4x1385=3324KB/s and Brasero is burning at the 4x speed, after starting at 2.4x. So please mark this as invalid, although I'll make a feature suggestion that Brasero should report the media speed, since it appears to using it to determine burn rate. For example, for my RiDATA 4x media (printed right on the disc, itself), dvd+rw-mediainfo reports: GET [CURRENT] CONFIGURATION: Mounted Media: 1Ah, DVD+RW Media ID: RITEK/004 Current Write Speed: 2.4x1385=3324KB/s Write Speed #0: 2.4x1385=3324KB/s Speed Descriptor#0: 00/2295103 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s So basically RiDATA lied right on the disc. -- Basero does not offer correct speeds (only 1x) https://bugs.launchpad.net/bugs/257010 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
