Version: 1.91.0 (using 4.3.5 (KDE 4.3.5) "release 0", openSUSE 11.2) Compiler: gcc OS: Linux (i686) release 2.6.31.12-0.2-desktop I have a LG DVD burner verion HL-DT-ST DVDRAM GH22LS50 one a new PC which burns at 16x under winxp but under k3b it reaches speeds of 0.22 to 0.50 at max, info from /sbin/hdparm -i /dev/sr0 /dev/sr0: Model=HL-DT-ST DVDRAM GH22LS50, FwRev=TL02, SerialNo=K159C1L0536 Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=unknown, BuffSize=unknown, MaxMultSect=0 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no Drive conforms to: unknown: ATA/ATAPI-3,4,5,6,7 * signifies the current active mode during burning the buffer fluctuates a lot from full to almost empty
After posting this I remembered the BIOS option IDE/AHCI, so I changed SATA mode from AHCI to IDE and low and behold burning speed is up to 11x, so I guess I will leave it at that, unclear now to me if its a bios issue, linux kernel issue or k3b though
Same problem on openSUSE 11.2 for x86_64. Used to burn DVD isos at 4x very quickly.

I switched the bios to IDE and that improved it so as far as I am concerned its sorted as as said in #1 (forgot about this report)
