I am currently writing a TV-app (now in pre-alpha state :) ) and
want those infos to automatically switch to the appropriate zoom mode,
so setting those values manually doesn't help very much. I've already
read that the VBI-support is on the to-do-list, but wasn't quite sure
if WSS may work anyway. Are there any plans to implement it in the near
future?
