This is a new acer from the store. I started it up to make a system backup disc. followed all the on screen promps. But after I click start to burn the disc, the drive opens up & I get a message saying to insert a disc & press start to continue. So I do it & the drive opens up again. I then tried to just load a pre recorded movie DVD and the same thing happens. How do correct this problem. What is causing it. Any help I can get please. Im new at this.
