Hi. I have the same problem on Kubuntu 9.10. DVD burning is extremely slow.
Details: dvd: sudo hdparm -tT /dev/sr0 /dev/sr0: Timing cached reads: 512 MB in 2.00 seconds = 255.91 MB/sec Timing buffered disk reads: 4 MB in 3.22 seconds = 1.24 MB/sec At least harddisk is ok :-) sudo hdparm -tT /dev/sda /dev/sda: Timing cached reads: 4096 MB in 2.00 seconds = 2047.85 MB/sec Timing buffered disk reads: 270 MB in 3.02 seconds = 89.48 MB/sec dmesg | grep ata [ 0.000000] BIOS-e820: 00000000cfeb0000 - 00000000cfebe000 (ACPI data) [ 0.000000] modified: 00000000cfeb0000 - 00000000cfebe000 (ACPI data) [ 0.000000] #0 [0000000000 - 0000001000] BIOS data page ==> [0000000000 - 0000001000] [ 0.000000] PERCPU: Embedded 30 pages at ffff880028022000, static data 90720 bytes [ 0.000000] Memory: 3917816k/4980736k available (5043k kernel code, 788228k absent, 274692k reserved, 2810k data, 652k init) [ 1.457405] Write protecting the kernel read-only data: 7180k [ 1.559651] libata version 3.00 loaded.

I googled the Net and found a lot of similar problems with slow dvd and recipes for fixing. Neither of these recipes helped me. Happy New Year!
