[gentoo-user] OT: DVD recording speed is awfully low

[gentoo-user] OT: DVD recording speed is awfully low

[Matias Grana]

I'm recording a DVD which is capable of doing 16x, using k3b. Before
starting, k3b explicitly said:
Writing speed: 22713 KB/s (16,40x)
but then, it began writing at speeds between 0.5x and 0.9x, so it took
me about 2 hours to record.
Before I begin writing the next 2 dvds I need to, I beg for any advise
as to how correct this.

Thanks in advance,
Matías

Is DMA enabled for this drive? Does anything odd appear in dmesg?

I think this is the relevant part of dmesg. I don't see anything strange here,
but perhaps you do.

Also, when I booted there was a message saying that it couldn't load ide-cd. I
can't find that message now. I don't have ide-cd compiled into the kernel nor
as a module, though.

What say "hdparm /dev/hdb" ?
