Earlier versions of the Magix video programs come with a "Burn Profiler" program for fixing burner problems. It may well do that, but it has also caused huge problems with Windows. Therefore, I recommend that you only use it if it is recommended by Magix Support.
A thread about the Burn Profiler has been posted by Magix here.
If you do use it and your system dies, you can attempt to recover Windows using this guide, provided to me by David. This particular guide is only applicable to Windows XP.
