Costco currently has a coupon deal where one buys a 100 pack of TDK blank DVDs and gets another 100 pack free. I plan to buy a new iMac in the next month and want to make sure I buy the correct type. My DVD recorder works with both, but IIRC Macs don't, so which is it, DVD+R or -R, also what's the real benifit of RW DVDs? Hope these questions aren't too stupid
