A single layer DVD is 4.7 GB

A dual layer DVD is 8.5GB

Single layer BR is 50GB Dual is 100GB

Easy math.

on a tb?
well its like this
217 dvds and
if its a single layer blu ray disc – 50
and if its a double layer – 25

you need a blu ray dvd player or a ps3..haha

Nope, you need a Blu-Ray player to play Blu-Ray discs.

Yes, you need the player.

Yes you do. However, a playstation 3 would also do the job

I'd wait awhile til the price comes down.

There are some Blu Ray players that play HD but you may have trouble finding one.

the Answer is simple ..YES.
Samsung is the best..

For most models available i would say it can play the two, but just two be sure enquire with the merchant or read the product description before the purchase because they arent cheap ya know.
