Current cdrecordes don't have fine tuning of low speed (1x, 2x, ...)
According to:

your CDR should do at least 4x, 8x, 16x (and in range from 20X upto 48X
covered in 1X steps).
Try then 4x or 8x. On my P200 I have PXWR 8/2/20 and I don't have any
problems at 8x. I think that 24X (3600KB/s) is doable even on P200 (on light
machine load) but it depend on your HDD speed - my HDD IBM-DTTA-350840 in
hdparm test has >8MB/s.
You should connect hdd and cdr to different IDE channels and turn
on DMA for HDD and CDR. I use for disk (only, because my cdr is on scsi:)
hdparm -c1 -m16 -p4 -u1 -X34 -d1 /dev/hdb
Use burn-proof technology with cdrecord option driveropts=burnfree :)
