> Presumably though, the captions were authored for 4:3

This is an incorrect assumption.  We get CEA-608 captions that were produced using a 16:9 asset.  The person who did the caption work was working in a 4:3 grid within the 16:9 video window.  When we receive and process the incoming asset, we will know how to present it.  However, in W3C-TT, there is no way to convey that presentation information to a client.  This is the root of our issue.
