For burning music or mp3 cds for your cd player, iTunes is the easiest way to go. To burn files on to a cd, insert your blank disk, drag the files you want on to it, then double click the cd icon and press the burn button in the corner of the window that comes up. You can also use the File > Burn Disc command. This also works for burning data Dvds. For burning movie discs for your dvd player, I've only used iDVD. It may not be very fast, but for me it always works, and it's super easy to throw together a dvd menu.
