DVD Media formats whats pro and cons?

[preynol1]

Hi, What is the difference between DVD-R and DVD+R blank media?

Which is good for standard backups?

Simply plugging those terms into google will give you a wealth of information on them. Most simply, +R is more similar to pressed DVDs and can be read by some older DVD players that can't read -R, but in terms of media quality, longevity, and compatibility, brand and pressing plant is far more important than +/-.
