Kazaa is well known as Illegal Software.....that's not the half of it.....it's also associated with Spyware. You (anyone) would be well advised to get it off of your PC ASAP.
As for a good all around CD burning Software package......NERO is the bomb.
It will burn any type of CD or DVD. (all legal versions, of course)
I personally use 5.5 because in ver 6 they took out the great little "Wizard", which makes burning a CD or DVD a piece of cake even for the total novice.
But, with or without the "Wizard", NERO is still the best.
Buy it if you have to, but get it.
Good Luck and God Bless,
