The other day I changed the channel to the Universal channel and it was suddenly showing it in 4:3 instead of the normal 16:9. The picture is squashed to fit into 4:3 and I know the shows normally show in 16:9 so it's not a case of the shows being filmed in this ratio. I checked my TVs settings, they hadn't changed and no other channel is affected. It's starting to drive me a bit crazy as I was watch this channel regularly and know it shouldn't be like this, just can't figure out what to do. Does anyone have any ideas?
