I was thinking of purchasing a dual layer burner, but I was curious on if its worth it for anybody might have it? I read up on it seems most people use it to back up 360 games, which I don't even have I use Ps3. I was wanting to use it to burn movies that might be larger than 4gigs or backup one of my movies that is dual layer. So if anybody has any thoughts or insight please feel free to share with me thanks!
