I am new here. I am an old man who knows little about MBP except to load and print photos.

I am going cruising and will be at sea for 8 days.
I am bringing my MBP with me.
My wife likes to practice singing her karaoke videos during our vacation.
I put the karaoke disc into my MBP but it will not play.

Please, does anyone know what software do I need so I can play those disc?

Thank you.
