Re: 16:9 to 4:3 Converter?
There is actually no such thing as a 16.9 picture. All transmissions from broadcasters are 4.3. To make them 16.9 they use an anamorphic process, which as Brian says makes the 4.3 picture elongated. You simply get a wide angled lens then focus it on a smaller area. Then you get another lens then refocus it back. Or that's how they did it in the movies! In TV terms they squash the image on to the 4.3 frame. They then have a signal built in, which makes a 16.9 set switch to widescreen, and is switched off for standard 4.3 transmissions, which are not squashed. In fact some Sky channels frequently get this the other way around!
The other way is to add the black bars to the standard 4.3 transmission picture so it is framed right. Then send a widescreen signal to a TV to switch it to the zoom settings.
Depending on the age of the 4.3 TV, some have settings to switch the elongated picture to 4.3 or a zoom setting. Very old models will not have it at all and will show a elongated picture, or a black box all the way around.
It's a bit like trying to get shut of the black bands on a 21.9 picture on a 16.9 set. You can sometimes Zoom in, but you will loose some of the picture. Or you put up with the two black bars!
By the the way isn't 4.3L meaning 4.3 letterbox?
So if you want to loose the box switch it to 4.3 only.
