Playing around with the picture modes on my new Sony KV32FX66, I got into the habit of switching to 4:3 mode in order to see what is really being broadcast. I can then see the stuff that really is 4:3 and the stuff that has black lines on top and bottom, so must be wide format. However, I've found that switching those to 14:9 mode, I still see thin black lines top and bottom, but switchnig to 16:9 mode takes the picture to the left and right screen edges, but loses some of the top and bottom. This suggests to me that the broadcast is somewhere between 14:9 and 16:9 in size. Am I right Seems like a strange choice of size - 4:3 or 16:9 ought to be the two possibilities? Surely stuff that's filmed in wide ought to be broadcast in 16:9 as the size I'm getting is no good to anyone. This is just some programmes - others (like movies) are obviously true 16:9, and I've got letterbox DVDs which are 2.33:1. So why this strange broadcast size?
