Maybe it is just me, but Im a little confused
If you are looking for a CD burner-that is hardware. It is not something that you can download. It is a physical piece of equipment, that you hold in your hands. Another example of hardware would be a keyboard.
If you are looking for a software application that you use to burn CDs, you have to have a CD burner first. If you do, then I would use what came with your burner (or computer, if it was already bought with one).
If you are looking for an alternative one, then there are a few things that need to be asked:
-What do you want to burn? Music for a CD player, videos for a DVD player, back-up of HD, ect...
-Is speed more important then consistancy?
-Is there a reason why you want to change, if you already have one?
-You mentioned that you want a free one, but if you found one that you like, and was using it as a trial, would you be willing to purchase the full version?
-Is your computer more then 5 years old?
-What type of internet connection do you have? Dial-up, DSL, Cable, ect...
If you can help me out, I can help you out. With a little bit more information, I know I can find what you are looking for.
We are all curious like a cat. We wonder, we ask, we learn.
