"New Burn Folder" vs. Burn app

[celticpride678]

I am deciding between using the New Burn Folder option in Mac OS X or the application Burn. I have a few questions:

1. Will New Burn Folder be readable by Windows?
2. Can anything be placed in the New Burn Folder?
3. Will the actual folder burn to the disc or the contents of the folder?
4. Can it burn .ISO files?

Thanks a lot!
