You have not said the TYPE of CD or DVD you are trying to play. Your manual will clearly state what can be played and what cannot. ALSO, some mfg's like mine (samsung blu-ray) provided software or firmware updates you can d/l to flash drive or burn on cd and insert. Check manual and your mfg websit for what's available.
