Your laptop should have Windows Media Player pop up as an option to click on as a program to play the cd once the cd loads.
However, you certainly can use VDJ8 to play off of a CD.
However, I will say this: You should always carry a dual CD Player with you...at minimum a single disco, OR WALK MAN CD PLayer plugged into the Phono or AUX on your mixer would even be sufficient. Back in the 90s, some DJs used walk man CD Players to play music.
I use a Dual CD Numark Mix Station on all events, and carry my CDs with me. I play about 30% of my music from CD. I am doing a Mitzvah tonight...I guarantee I will play many songs off of the more recent NOW CDs tonight such as Now 53, 54, 55, 56. I'll probably play Icona Pop off of Now 47, maybe even Call Me Maybe off of Now 43 even though I have those songs on my laptop too.
I advocate still using CDs at events today...at least as a back up.
