I want to buy a DVD Writer

[Marco234]

Sorry for language mistakes : I'm french.

I want to buy a DVD writer, but I have questions :

The products don't give informations on the DAO, raw, overburning, ... supports. Is that all the DVD writers are the same ? It would be strange because it's not the case for CD writers...

If not, where can I find a list of DVD Writers wich are indicated for the copy of protected CD ?

Thanks Marc
