I have the original DVD and since it's single layer not dual, I just figured that the single layer 4.7 GB would be more compatible.
I was burning the DVDs with ImgBurn which is recognizing the DVDs as 4x and burning them at that speed even though I selected 1x. I'm going to try a different computer and a different program.
I also have a DVD in the car with the doors closed, but unlocked and the key with me and just left it to see what happens as per your last recommendation. Will update as soon as something happens.
