Now I don't think the definition of DVD is very high. What is higher than the definition of DVD and can be seen on TV?...
If you do not use Blu ray discs and use ordinary discs, you can't achieve HD standards. The so-called good horse with gold saddle. Ha-ha
Blue light (Blu-ray DVD) is the best choice for you, there are sales in many stores now, and the price is not expensive, the Blu ray DVD and Blu ray discs, can reach the standard of 1080i, Blu ray discs are available in the professional video store.
Computer ah! There are lots of HD movies! Audio can be connected to the original home theater system! There is a slightly larger monitor on the OK! That must be much clearer than DVD!
