ive noticed that when i made a cd using a CD-RW it plays upstairs in my panasonic stereo and not downstairs in my mums cheapo alba mini system, now theres nothing strange about that is there? BUT my mums alba seems to play CD-R's? i thought if it didnt play RW's then it also wouldnt play R's either but obviously not? what is the point of being made to play R's and not RW's aswell?
