Hi there. Acard also have adapters for ATAPI devices. They allow you to use SCSI, so if you use that you won't lose much CPU time;) Check out the features of each card on their site, they specify if the card is more oriented twoards ATA HD's or ATAPI devices. Then go to eBay and buy the card there, they're cheaper, and from time to time some appear. There's a couple of them there right now.
Also, softwarewise, FryingPan is also very cool, haven't tried it (yet) but it's the best one for DVD burning on the Amiga from what I've heard, it even supports Blue Ray DVDs;).
