Why is my Sony DVD taking so long to read discs?

My Sony DVD player is fairly new, if I can say that after having it for a couple of years. I started having problems a while ago with its reading of cds and dvds. I thought it needed to be cleaned. So I cleaned it. The problem was still unresolved.

I put in a cd and it takes sometimes 10 minutes for it to play anything. During that time, the screen will read as loading. And sometimes it will say Cannot Play This Disc. I put the cd in again because I know there's nothing wrong with the track, and then finally it will play. Sometimes when I'm in the middle of watching a dvd, the screen will blink to saying 'USB port' and I lose my place in the video.

Why is this happening? Why is my DVD player moving so slowly? Is there any place I can go to have this fixed immediately?
