I am trying to burn with a single drive. My old computer was a dual drive and i had no problems. But I am having trouble with the single drive. First- I put in a movie click on copy dvd. Second- i go through the steps. Third - It starts creating a dvd, when finish it ask for a blank media to write to. I replace the movie dvd with a blank dvd and it says to put in dvd media. It's like it not accepting the blank to write to.
