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.
