Bet it's not using DMA: try hdparm /dev/cdrw where cdrw is your CD burner, and look at the using_dma line. If not, you can use hdparm to turn it on temporarily, and look at /etc/rc.d/rc.sysinit and /etc/sysconfig/harddisks* to fix it permanently. Note that the kernel decides not to use DMA with devices for a reason. There may be the possibility of data loss. That probably isn't the end of the world for a CD-RW, but I wouldn't put a hard drive containing any data I cared about on the same cable.
