There is no trick, if your DVD writer won't burn DVDs as promised then phone the maker's helpline. There could be a technical problem or fault that has to be looked into or repaired.
You have not said what make or model your DVD writers is or what burning software you have tried to use but your question seems to indicate that your machine is simply not working.
If you know your machine works then come back with more details about it.
