The usual software for doing what you want to do almost always comes with the CD burner. The two main programs that i know how to use are:
Nero, which is usually found in a folder in the programs section of your computer called "ahead nero"
Or CD Creator. Both programs are pretty easy to use.
What software are you using now?
You don't say if you are using a computer with a CD burner that came with it (software should have come with it, too) or with a CD burner that was installed at home (A CD with the software almost certainly came with the burner). What is your operating system, Windows XP, Windows 2000, Windows Millenium, Windows 98, or Windows 95?
