Wow... you must have been bored :). Actually the scenes without music/sound were either duplicates and/or the sound from a different file was played when that movie was played, (if my memory serves me correctly). As for the letterbox... you actually see more in the letterbox format than you would in "full-screen" as the movie scenes in WC4 were actually shot in 35mm film and the aspect ratio of film is different than that of a computer monitor and/or TV. To make the film full-screen we would have had to perform what is refered to as a "pan & scan" which would actually crop the image thus losing some of what was shot. The same thing happens when feature films are formatted for television, which is why many DVD's come in the original letterbox" format so the viewer can experience the orignal theatre presentation. As for the Borderworlds poetry...!!??? Sounds like an easteregg from one of the artists or TDA's on the project.
