Now you can create, edit and archive home movies and digital photos while storing and accessing data from one disc. DVD discs capture all digital data brilliantly, and are large enough to hold oversized digital movie files. Sony DVD for one-time recording is a relatively inexpensive way to store data and prevent accidental erasure. They can hold 4.7GB of information, which makes it possible to record 120 minutes of MPEG2 video footage with outstanding picture quality.
