The light weight decoder is light weight because it does not even support 
level 1.5 teletext (proper international characters).

No, I see little benefit of it, because if there are multiple subtitle 
pages, then they will get mixed up. It is less error prone if the user 
specifies the page. If somebody thinks it is useful, it can be added 
relatively easily.

Sure.
