I just got new Plextor 708A burner (Firmware 1.06). I was using the Sony 510A before and Encore 1.5 was not displaying DVD burning speed. Instead it was displaying the CD burning speed 4x -24x. When I placed the Plextor 708A the Encore 1.5 correctly displays the DVD burning speed 1x - 4x, however, I was not able to burn at 1x. The project is 4 Gig and it took 18 min to burn it, so I know it was burned at 4x. By the way the same project was burned at 2x using Sony drive. I tried to do the DVD copy using the Roxio Media Creator at 1x and it took little more than 1 hour to copy the DVD. I have read many posts stating that when creating master DVD it is better to burn at 1x. Is it Encore problem or burner problem?
