My wife has all these CDs full of digital photos in our fire safe. I got to thinking what a shame it is that we've never used the DVD burner on our computer, and figured that if we could save some space with storage of the photos...why not try it?

Tonight I got a pack of DVD+Rs. I also noticed that they sell DVD-Rs. I see now computers advertise DVD RW +/- drives, and I got to wondering if I got the right kind of DVDs for what I want to do.

Who can clue me in as to what the difference between the +/- is?
I got the DVD Rs because I wanted to make sure they work the way I think they will before I invest a little more in RW.

Thoughts?
