What does the DVD+R/RW format provide that the -R/RW format does not? Frankly, not too much. You can add and delete titles with +RW (you can't with -R). You also have the ability to instantly use or eject +RW. You have a format step with -RW. You can record one title on a home DVD recorder and a different title on a PC with a +RW. A PC can also directly edit on a +RW disk. The single biggest difference is the availability of new dual-layer DVD+R/RW media and recorders that allow you to store up to 8.5 GB of data on one disk. Virtually any new DVD burner will burn -R/RW or +R/RW, but only newer dual layer burners will burn this new higher capacity format.
