From: csj@gmx.co.ukThe same command as above Note that with dev=ATAPI: you will never get DMA and writing is soooo slow.I thought that had been fixed, I would swear that cdrecord uses DMA with ATAPI and 2.6 kernels. Now I have to go back and check, I replaced the CD-R drive with an unsupported DVD unit which doesn't work with anything.I'm a bit confused myself. The documentation isn't too clear about the difference between dev=ATA and dev=ATAPI. I tend to use dev=ATA with linux 2.6.This is the general problem with Linux :-( They invent a new incompatible interface every even year.... If you have problems, ask the Linux kernel people.
How would the kernel people know what your software does. to restate, cdrecord seems to use DMA with 2.6, write audio very fast with little or no CPU use. Does pro-dvd also use DMA? That's a yes/no question, although any clarification would be useful.
