I have a LG GE20 DVD Rewriter Is a DVD+RW disc a format that is editable and suitable for this unit?
The LG G20 DVD Rewriter is an advanced external burner that supports 'editable' Rewritable DVD+RW disk.
As a generic comment, not all writable/rewritable media are made equal and problem with branded & unbranded disks are not uncommon, so stick to brands that work for you for your specific unit!
