What's a good DL DVD Burner to buy? When I do get it, is it a good idea to burn something besides dual layer media? I have a Playstation 2 and I was told that if I want to prolong the life of the console that I should play only PS2 games. Don't play PS1 games, don't play DVD movies and no CD music because the console switches lenses between all the media. I do that for my CD-ROM/DVD-ROM/CD-RW/DVD-RW too. Is this also the case for the DL DVD Burner?
