4x DVD+R discs for newer DVD+R/+RW drives consists of write-once, single-sided discs that store up to 4.7 GB of data and approximately 120 minutes of DVD quality video--that's more than six times as much data as will fit on a recordable CD. You can transfer your home movies from VHS or 8mm cassettes, back-up computer hard drives and large files, or stuff them chock full of MP3 music files and JPEG image files from your digital camera.

The discs are backward-compatible with older, 2.4x DVD recorder drives through the use of a simple firmware upgrade for the drive in question, which you can downloaded at
