Hello, I have a Panasonic E30 DVD recoder. I am still new at this and I have no idea what 1x 2x, 4x on the DVD-R's mean. Can someone explain this to me. All I am doing is putting my VHS tapes onto DVD. I am not burning them or using anything on the computer. Would I still need to worry what X to buy? Is higher up (4x) a better picture or something? Any help would be great. Thank you.
