Compatibility Issues with Existing DVD Drives
Although early compatibility tests suggest that double layer media can be read successfully by most DVD set-top players, compatibility issues are a much bigger concern with DVD drives in PCs. If you want to use a double layer DVD+R drive to create backups for use in other systems with DVD rewritable or DVD-ROM drives, it's important to check with the maker of your existing drives to determine if they can read double layer DVD+R media. The best general recommendation is to insure that all of your existing drives are upgraded to the latest internal firmware revision since most of the time, firmware upgrades will correct any issues with reading DVD+R DL discs.Check the DVD+RW Alliance Product Upgrade Portal www.dvdrw.com/productupgradeportal/dl.htm for links to firmware updates to existing drives.
