I bet when DVD came out there were similar whinges from moaning old gits
DVD was out for ages before people decided they wanted it.
It's going to be the same this time. People don't like change even when it's good for them.
Trust me, if you have an LCD HDTV you will notice how much better HD content looks than SD. You can see every flaw in the compression. When I first watched a DVD on it I thought my TV must be broke it was that bad. It wasn't until I searched on the internet that I found out it was normal.
If you have a HD TV, you need HD content. It's a simple as that.
