Turn on NeroVision then add the file that you want to convert. If it is Nero7 then it will decide on it's own what quality it burn at to make it fit on one DVD. It takes a while to convert+burn (approx 2 hours depending on how fast your computer is)

DO NOT run any other programs while making it. NeroVision draws every drop of juice out of your processor while converting (100% CPU)

Just put your empty DVD in the burner. Start the program and leave it alone until finished
