and the general theory of relativity suggests nothing can travel faster than the speed of light

It's actually Special Relativity that sets the "nothing can travel faster than light" rule. General Relativity describes the geometry of space. If you sit just on the event horizon of a blank hole, light for you would still travel at the speed of light as Special Relativity says that light travels at the same speed for all observers. From a General Relativistic point of view however, an observer way outside the event horizon would see you slowed down to the point of not moving. This is because, as Janoskiss said, that it's the extreme curvature of spacetime that your in that's causing the dilation.
Another simpler way to think of it is that the escape velocity on the event horizon equals the speed of light. Beyond (inside) the horizon, it's greater than
