The "tracks" you mention are really only two thin white pieces of either plastic or fiberglass looking tubes (they look like long thin pipe cleaners) that are on the sides of the drawer. My drawer was not working at all when I got it because those tubes had come loose. You must have them in correctly or the door will not slide properly. If you cannot figure out how to do it, e-mail me and I can call you and coach you through it, Once installed right, the door should give you no more problems.
BTW, I think it is a Mickey Mouse mechanism for a $9,000 player but it actually works smoothly when they are in right.
