The only sure way to know if a cd will play on any given dvd player is to try it.
I have a mitsibishi (?spelling?) dvd player and sometimes it won't play a cd I've created with Nero and then there's times it will. Like wise with movies on dvd-r discs I can play some but not all. My dad's dvd player has played everything I have put in it! and it was a fraction of the cost of mine!!
The discs will always play on the computer.
