Software vendors are quick to add the support for the double layer recording, Sonic Solutions being the latest. Sonic’s production line expands from CD/DVD burning to professional DVD authoring. Their DVD authoring software has earned a good reputation and the RecordNow! is a long time favorite of DVD-R users when burning image files, as it is able to verify the resulting copies.
Sonic's MyDVD®, Sonic PrimeTime(TM), DVDit!® and RecordNow!(TM) consumer applications as well as Sonic's "Hollywood" professional applications, Scenarist® and DVD Producer(TM), are the first to take advantage of this unique technology to create DVD+R Double Layer discs that can hold four to eight hours of video or up to 8.5 billion bytes of data on a single disc.Source: Sonic Solutions
