Ok, I've noticed that most don't like Memorex. I am so new to this it's not funny. Sorry. At any rate, where we bought them from we can't take them back to. Why? Because we bought them when they were on sale ...while we were out of town. I have a Samsung SH-W08A. I updated the firmware. The disc still doesn't work. I am told to insert blank media. What does that mean? I looked up on Samsung's site and my DVD burner can burn up to 8X. I use DVDClone2 and set it for 8X and then tried it with 4X. Still doesn't work. What do I do?
