I just got a "new" iMac, 500MHz G3 20 gig HD 384Megs of ram 16MB graphics card, with CD-RW. any ways i set up OS X on it and put some songs in iTunes then i tryed to burn a CD, after 3 errors (each half way through burning the CD) i gave up. it shows a error window "unknowen error occured (-50)" what is up with that? its a new computer! (never been opend b4, sraight out of the box) why is this happening? any help would be appretiated. its gone through 3 CD's and im not willing to waist any more. i thought that the internal iMac CD-RW would work with iTunes, it does on my friends iMac. i tryed to do a hardware check and it dosent check the optical drive, i tryed to slow down the burning to 2X but no avail, same error message. please help!
