as far as dvds go
what does dual core mean
thanks

i meant dual layer

[Buenchico]

It means exactly what it says.

There are two layers on the disc, each of which holds data. The top layer is semi-transparent so that, while one laser beam reads data from that layer, another laser beam can be focussed through it in order to read data from the bottom layer.

..and they can hold 8 gig of data rather than just 4.

...scuse me 8.5 gig rather than just 4.7 !
