Hello, I have just started to copy DVD's and need to buy some blank ones. Just wondered what the difference is between dvd+r and dvd-r - does it matter which I use to back up my discs? Also, if anyone could recommend a good website which will give me a good deal it would be much appreciated. I've looked on ebay and theres 50 Sony for £26, is it necessary to get a well known brand or is it OK to settle for a cheaper less well know company? Thanks for your help and time in advance!
