Whats wrong with the dvd player in my yukon?

It turns on and works, however, when I put in a DVD it just loads forever and it won't eject the disc unless I turn it off and turn it back on, and when it does spit the disc out it doesn't spit it out all the way and I have to pry it out with tweezers fast or it just sucks it back i
I've looked in the Manuel for the car and it says that it could be that the parental control may be on and to turn it off but I cannot for the life of me figure out how.
I just bought this car and unfortunately didn't notice that there is no remote for the DVD player.
Also, I'm not very techni-capable so any tips help.
