I would like to render to an audio and video stream. When I go to Make Movie, I find a choice for rendering a DVD compliant video stream. But what happens to the audio? I will be using DVD Lab for creating the DVD's and it splits the streams anyway, so I might as well start with two to begin with. So my question would be, how to I get the audio stream? And is rendering faster if you split the streams or does it stay about the same?
