Firstly, edit out your serial number before someone pirates it. This is the first version of Nero7, it contains some bugs, I would uninstall it, run this clean tool to remove all traces http://ww2.nero.com/nero7/enu/Nero7_CleanTool.html and then install current version from here, remember to keep a record of your S/N. http://www.nero.com/nero7/enu/nero7-up.php These arent top quality discs, try Verbatim or Sony that are made in japan Slow burn speed to 4X
