Don, I also use CDBurnerXP and it works fine. I haven't done anything fancy, just burn cd's. If you are talking about tweaking audio, that's another matter.

I don't know if it's the same these days, but in days of old, you are less likely to have read errors (by the user) if you burn at slower speeds. Which I do. However, burned cd's are always suspect to having play problems by some users. Of course, you could always tell a customer that you guarantee the product in case of play errors. My own 2008 Nissan Titan truck's player won't play burned cd's correctly sometimes. Makes me mad!
