Strictly speaking, the term "DVD Authoring" refers to the process of making video playable on a set-top DVD player. The video must be MPEG2, of compliant resolution, it must not exceed a combined (audio/video) bitrate of 10.08 Mbps. Framerates of 25 fps (PAL), 29.97 (NTSC), or 23,976 (Film framerate, requiring pulldown flags). Blah blah.
