He means that you should export a quicktime file of the entire timeline. Then export an EDL (of course reduce the timeline to one track first). Put this long video file in the Media Pool and preconform with the EDL. This works very well, we use it all the time where I work, avoiding all kinds of surprises in the timeline.
