do you need a special package to burn dual layer dvds?

ive got dvd decrypter, will this work on dual layer discs if i buy a external dual layer burner?

 

I use Nero for mine. Never tried anything else.

 

yes decrypter will work, but imgburn is the updated burn engine to this and it works as well and is also free. Just don't buy cheap discs verbs are the best but are a little dearer, about £1.70 a disc if bought in 10's.
