Hi, I'm going to use dual layer DVD+R discs to backup my iTunes and iPhoto libraries. I was checking the prices of dual layer discs on the media site I buy from. I prefer using brands I know like MAXELL, VERBATIM, etc. , but this site has a brand called MEDIARANGE that is half the price of the others. can anybody tell me if this is good brand? are the DVDs reliable? why so much cheaper? should I stick with big names? are all blank media really the same anyway? I rather be sure I have a good backup than worry about the money (especially with iPhoto). thanks.
