Format a DVD +R DL onto a LG Burner

LG makes many different models. DL disks are dual layer, which are used for video DVDs. They do not not need to be formateed. Write once media like DVD+R, DVD-R, etc are not usually formatted unless you want to use them like a write once floppy. If you are trying to make a data DVD (for use with a computer only), then I don't think you want to use dual layer media.
