Bug Description
I have just purchased a new Samsung SH-W162C/BEBN.
According to the specs, it should be able to burn DVD-R's at 16x. When I tell k3b to burn a DVD, it first sets the speed to 8.02x, but it doesn't manage to burn faster than 4.4x. This drive is capable of various fast UDMA modes, so there's no reason for any particular limit on speed, but I don't know how to diagnose this.
Dapper seems to be using SCSI emulation (which I thought was deprecated for CD burning), so I can't get anything from hdparm for it.
There must be some aspect of my hardware that Dapper isn't detecting right. I'm using a brand new P4, 3.0GHZ, on an ABIT IL8 motherboard.

If I have k3b create an image first, the burn speed I get is a little over 5x. I'm not maxing out either hard disk throughput or CPU utilization.
Also, FIFO buffer and Device buffer meters show nothing.
