Reply:use a CD-R(recordable instead or re-writable)?
Reply:Some CD players won't play RW type of CDs, they will only play R types. There should have been an option at the start that lets you choose if you want to play it on other CD players other than your PC. Try burning a whole lot of songs at the one time onto an R CD, then playing it on another CD player to see if this works.
