                                                          The vast majority of DVD players are able to play CD's.  The opposite is not true.  A drive labeled as a cd-rom or cd-rw drive will not under any circumstances play a DVD.  The same is true with Blu-ray drives, in the majority of cases, they will play DVD's and CD's, but CD and DVD drives will not play blu-rays.
