My XBOX and PS2 backed up games, all range from DVD + - R's and RW's, and they all work fine on all those systems. I used to own one of the early HP 100i dvd burners that only burned DVD+R media. About a year ago I bought a Pioneer DVD+-R/RW Burner, and that thing is just awesome! Go Pioneer!! (Waiting for the Dual Layered Burners to be released!) mmmmmm........
