Recording TV Programs Using Double-Layer Technology and Media (Select models only) Double-layer technology gives you almost twice the storage capacity of a single-layer DVD and the storage equivalent of 12 CDs. Double-layer DVD media can store up to 8.5 GB* of data. You can record on two "layers" of one side of a DVD. Double-layer technology uses two thin, embedded, organic dye films for data storage separated by a spacer layer. Each layer has different optical properties. n Double-layer media compatibility will vary with some home DVD players and DVD-ROM drives. General information about double-layer DVD+R discs: ■ You can record 3 hours of DVD-quality video or 6 hours of VHS-quality video, without turning over the disc. ■ This disc can hold up to 8.5 GB. This almost doubles the standard storage capacity of 4.7 GB for the single-layer DVD+R discs currently available. ■ Double-layer writing capability is supported by RecordNow! and WinDVD Creator. These are CD and DVD recording software programs that came with your HP Digital Entertainment Center. ■ Double-layer DVD+R discs can only be written to with a double-layer DVD+RW/+R drive. ■ These discs cannot be erased or written to again. ■ You can use these discs to back up your hard disk drive files. ■ These discs are able to play back in most commercially available DVD players. *GB is defined as 1 billion bytes. Actual formatted hard disk drive capacity is less. Recording TV Programs 135
