Help with avi2dvd files

I have used avi2dvd software to create the following files:

AudioStream 1 MP3 2CH
BeSweet_AudioStream 1 MP3 2CH.ac3

What do I do next? This is my first attempt at this, so respond slowly. I want to put on DVD. Do I have to dycrypt or do I burn. I have nero and clonedvd2.

Please help. :confused:
