Hi,
I am using a ASUS DRW-24B1ST firmware 1.04. This is the latest firmware. There is a long story behind this drive's firmware which you can read about here: http://club.myce.com/f87/something-odd-just-purchased-asus-drw-24b1st-firmware-now-1-04-man-09-2010-newegg-317360/
When I try burning to a DVD-RW using 1x speed it burns at 4x speed instead. Here is a log for your review:
