ok, i can buy and rent dvd movies but i am clueless when it comes to purchasing them for backing up my pc (aside from the fact that this would be my first time), i am clueless.
with that said, can someone tell me the difference among these:
dvd-ram
dvd+r
dvd+rw
dvd-r
dvd-rw
i know 2 of them are readable and 2 are read/write but i dont understand the plus and minus signs nor do i understand what a dvd-ram is. can anyone clarify this and bring me up to the 21st century?
thanks
