The better way to burn a cd's under the new interface is
cdrecord dev=ATA:x,x,x
where x,x,x is returned by:
cdrecord --scanbus dev=ATA
I myself am confused over the difference between dev=ATA and
dev=ATAPI. AFAIK dev=ATA:x,x,x gives you DMA, while
dev=ATAPI,x,x,x doesn't. This is with the unstable version of
cdrecord. dev=ATA is probably equivalent to dev=/dev/hdX.
