How to burn a dvd after using the decrypter?

So I feel like i'm working in the dark here. After I decrypt a dvd from dvdfab I get a dvd file with a video and audio folder. So after searching and searching so I can just burn this dvd file to a blank disc finally I found a program that let me do this.. but after I got the new copied dvd to watch for myself well it only plays on the computer and none of the actually DVD players. So my question is in detail is there a simple free program that will let me burn the dvd file to a blank disc, that will actually play on DVD players? I dont want to convert the dvd file to a video format then burn it because i'm afraid it'll badly lose quality...
