SEE OUR 16 ORIGINAL DVDs  There are two TV screen shapes, the square box shape of older TVs that have a 4:3 screen ratio, called "full screen", and a new wide screen 16:9 ratio. Our full screen dvds were produced from 2005 to 2010 and the widescreen dvds and blu-rays were produced from 2010 to the present. Full screen dvds are lower resolution and best viewed on smaller screens. Widescreen HD Blu-rays are the best for large to very large screens or gyms. They are on sale but no extra discounts.
