A letterbox setting for those that have 4:3 TV’s would solve that problem, like there is on different TV boxes, DVD players and such. In my opinion it’s too much work to change the zooming manually to 92% all the time.
But I don’t know if there is a letterbox setting at the moment, I’ve just tried this a couple of days and it was too unstable for the moment for me to continue to use it until next version.
