2a. Importing the MPEG-2 file and corresponding audio file into a DVD authoring program

This generally involves dropping the MPEG-2 video file onto the timeline of the DVD authoring program, with the audio file (if you have one) on the audio track. Ideally, you should encode the audio in the AC-3 (Dolby Digital) format, which will reduce its data rate without significantly reducing its quality. The advantage of this is that the combined data rate of the video and audio (which is what ultimately matters to the DVD player reading the data on the DVD) will be lower. The only other audio format that is compatible with all DVD players is PCM (uncompressed), which has a data rate of 1536kbps (1.536 Mbps). Compressing the audio into the AC-3 format is preferable, as it will allow you to use a higher data rate for the video.

b. Making the DVD authoring program create an image file of the DVD (muxing)

When you are ready to burn your DVD, the DVD authoring program will entwine the the video and audio files in a single file, called the image file, that it will burn on the DVD. This process is known as “muxing” (short for multiplexing).
