*** This bug is a duplicate of bug 52666 *** This is a REALLY serious problem in Ubuntu. I have switched from WinXP and this is the only thing that really makes me angry about Ubuntu :/
Anyway, there are lots of people having similar problems - http://ubuntuforums.org/showthread.php?t=128721 . Plus, this bug ticket should be merged with bug #31709, as it's exactly the same thing. K3B has nothing to do with it, 'cause people are having this problem no matter which app (or what kind of writer) are they using - I personally have it in K3b, Brasero and Nero. But first things first -- I've got LiteOn SOHW-1633S ( http://www.liteonit.eu/index.php?option=com_content&task=view&id=36&Itemid=67&limit=1&limitstart=1 ) with BS0Y firmware. It allows me 16x burns on DVD+R blanks. And it does - in Windows. In every app - Nero, A120 - you name it. Burning full 4,7GB DVD takes no more than 10 mins in Windows. In Ubuntu, on the other hand, I have never managed to achieve speed above 4x. Usually, burning full DVD takes me 40 minutes or more. Here's my hdparm /dev/dvd (if it helps) /dev/dvd: IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 8 (on) HDIO_GETGEO failed: Invalid argument And hdparm -i /dev/dvd: Model=LITE-ON DVDRW SOHW-1633S, FwRev=BS0Y, SerialNo= Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=unknown, BuffSize=0kB, MaxMultSect=0 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 IORDY=yes, tPIO={min:227,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 *mdma1 mdma2 UDMA modes: udma0 udma1 udma2 AdvancedPM=no Drive conforms to: Unspecified: ATA/ATAPI-5 * signifies the current active mode Right now I'm using this hdparm syntax to set my writer: hdparm -d1 -c1 -a8 -u1 -Xmdma1 /dev/hda Anyway, I'm not sure if it's DVD+RW-TOOLS package problem, as I don't think Nero is using the package (and it's very slow too). Someone -- PLEASE, make this bug really important on the list. It's really an annoying issue. -- DVD burning is extremely slow https://launchpad.net/bugs/52917 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
