The main difference between blue ray, dvd's, and others.

Question

my family has been looking at the change we will eventually have to make. will a blue ray disc work in a dvd player? or vice versa? are there other things on the market that we should take an interest in? also, will both the blue ray and dvd work in old tv's that are not HD or updated?

Answer 1

Blu Ray is an HD format for DVDs. It will not work in a standard DVD player because it requires a special Blu Ray player. The Sony PlayStation 3 has a Blu Ray player built in as do some laptops. Also, Blu Ray players only work with HDTVs. Therefore, Blu Ray discs will not work on old TVs or standard definition televisions. Even if you update a standard definition TV with a converter box, this will not allow it to play Blu Ray discs. This will only allow it to receive a digital signal for local channels.

Answer 2

  One big difference is that Blur-Ray can hold up to 50gb whereas a regular DVD holds only 4.7 gb and double that if it is a double layer disc.
