I am getting ready to buy a DVD burner. I am unsure what the difference is between + or - R. My friend is telling me to go with +R like his, but the media for -R is so much cheaper. Can you take any DVD and put it on a + and - Dvd? Or certain DVDs can only be burned to + or -? I will be using DVD xCopy express. I am also wanting to start copying all of my old VHS tapes to DVD too. Someone told me about something called Dazzle... You being the experts, what would you recommend? Where is the best place to get the media too? Thank you!
