From a few long Youtube videos I just watched, the amount of information in the Universe is limited and based on the total surface area, not the volume.

  This is true. Maximum entropy increases with the surface area of a space, not its volume. This is well explained by the holographic principle.

    Surface area implies a boundary and something outside the boundary. Isn't the universe infinite? Where does this leave entropy?
