Am I being overcritical ... or does anyone else think the picture quality on some of the SD channels is totally unacceptable? I just watched channel 5 with big brother on and the picture as they were zooming in to the presenter looked like it was recorded on a very old webcam. I'm not exagerating - it was appaling. This isnt the only channel/program I'm seeing this on lately either. Image quality is way below anything anyone would have accepted on analogue TV 10 or 20 years ago.
