Most burners were produced over the last couple of years have primarily been multi-format, meaning, they will burn the -R/RW and +R/RW formats. If you have a burner that is single format, meaning, it will only burn the - format or the + format, please make sure you purchase the correct format for your burner. If your burner is multi-format, either of the two formats should work fine. For higher rated burn speeds, such as 16x media, your burner must be a 16x burner in order to burn 16x rated media. You can purchase higher rated media, such as 16x rated media for a 4x or 8x DVD burner, your DVD burner will just burn that media at a slower speed. Also, it is recommended that you upgrade your burner's firmware to the latest revision. For more information regarding firmware or compatibility, please consult your DVD burner manufacturer. Most DVD burner manufacturers will only list brand named media as being compatible, when in fact, most media manufacturers don't produce their own media to begin with. There are many reasons for this, but if in doubt, we recommend you purchase a small quantity initially to see which type of media works best for you.
