I was highly advised to get Ritek brand media after about half of my memorex dvd+r didn't play right on my stand alone dvd player (sony). I purchased 8x dvd+r ritek and they will not burn at the fraction of the speed that my 4x were burning at "very slow". I know I know change your speed setting to 4x tried that didn't work and that just upsets me more because that is why I purchased 8x to burn faster now I can't even burn at 4x please help. I am using already burned dvd just recording them through sonic since they are already the correct size and encripted already by shrink if it makes a differance. Please help I am desperate I am thinking of sending these disks back.
