I assume you want the video burned to a DVD for playback in a DVD player? You'll have to use something like Toast for that. You just select the Video tab, then select DVD-video under formats. Then just drag the file into the main window, if you double click it in there, you can set stuff like bookmarks and do any cropping you may want to do.
For the music, you can just use iTunes for that. Just create a playlist with the music you want and click the Burn Disc button in the upper right hand corner.
