How do i changed from 80 minutes to 120 minutes for copiying disc to disc?


Hi,

Whe i try to burn a dvd using (sonydru510a) from my dvdrom liteon i get a message that not enough spave only 80 minutes on the blank dvd.

How do i changed this to 120 minutes?

I'm using powerdvd or windvd.


I'm new at this so i hope this is the right forum. So confusing with all these different standards.
I searched the help files in everything and i don't see this option anywhere.

Thanks so much

Deborah
