No, I start watching nature programmes in HD to start with. Then I watch other programmes in SD. Its not the end of the world if the news has a water based scene, I do watch that in SD. Do you ever watch SD programmes?
Not all channels have an HD version.
So why get used to watching in HD, when you can't get for all channels in HD? Or do men not notice the difference when they have no choice but to watch in SD?
