Este sucessor do DVD ainda vai demorar ....
Este formato então..parece o DVD-RAM que tambem vem em cartridge's.

1º o DVD-R/+R vai ficar comum a ponto de toda a gente ter gravador em casa para armazenar dados como é hoje o CD-R .... e penso q só ai irá aparecer os 1ºs discos de 23Gb a serem comercializados.

E 23Gb acho pouco... idealmente o dobro porque assim caberia um filme inteiro em DV mais Audio .

Boas Audicoes
