Question about Televison & Video
A DVD player is an optical digital laser device, and it is far more complex than a device that may use limit switches like an appliance.
In your case I understood that the DVD is reading track list (TOC), spinning the disk in a first time, and then not engaging to read the DVD tracks (movie menu, chapters, etc.)
If that is the case, then you have dirty or damaged lens, that is one of the most common problems that you may get on DVDs.
A DVD or CD player works projecting a laser beam on the surface of a plastic disk.
The Laser beam is reflected from disk surface to the lens. The lens will focus on the reflected laser beam, reading data. While the spindle motor movement is coordinated by a controller, that will spin the disk according to what track the lens need to read.
The spindle motor will be started a first time to read the TOC (table of content), then the disk will stop displaying the chapter menu.
If the lens is dirty, opaque or scratched, the player won't be able to focus on the track, and you will get the player hanging on with 'DVD loading' on display and not reading the disk.
When it is a lens problem you can hear a whirring noise, meaning that the spindle motor is working. The whirring will last for several second before stopping and returning no disk, or hanging on forever with Reading Disk message.
Try first using a lens cleaner disk.
If the cleaner DVD does not work, the lens may be cleaned directly, using cleaning solution or isopropyl alcohol and QTips, following instructions on link below.

Lens cleaning may invalidate warranty, and if not done in the proper way, it can even cause more damage. Before attempting the procedure I strongly suggest calling the manufacturer at the number listed on the user manual.
