How can a +R and -R get marked as "great" for "playing video on a home DVD player but a +R DL and -R DL only get marked as "okay". How can a +R and -R get marked as "great" for backing up data, but a +R DL and -R DL are not even recommended for data backup? How can a +R, -R, and +RW gets marked as "great" for backing up data but the -RW only gets "okay". How can a +R, -R, +RW, and -RW get recommended as "great" for archiving photos, music, video, and data, but the +R DL and -R DL are not even recommended? And how can you only recommend +R and -R for distributing "large" files and not recommend the DL formats? I mean if it's LARGE you want DL. Duh. And I'm shocked they even recommend ANY "R" format for achival purposes. DVD-RAM is the only mainstream optical format I think is acceptable for mainstream archival use. Fucking marketing people. They wanted a fancy chart but can't even apply basic logic to it!
