Does the DVD start from the outside and read to the center, or the other way.

From the inside to the outside.

This.

Same as hard drives.

What about the 2nd layer?

There are two modes for Dual Layer orientation. With parallel track path (PTP), used on DVD-ROM, both layers start at the inside diameter (ID) and end at the outside diameter (OD) with the lead-out. With opposite track path (OTP), used on many DVD-Video discs, the lower layer starts at the ID and the upper layer starts at the OD, where the other layer ends; they share one lead-in and one lead-out.
