However, modeling the selection mechanism for multilingual programming  
is much more difficult than modeling the selection mechanism for audio  
description, so the problems of conflating captioning and subtitling  
apply here as well (with the twist that additional audio tracks take  
more bandwidth, so it is less likely for additional audio tracks to  
get muxed into the same stream).
