Slightly OT but, Smitsonian will only have 75 hours of HD programming for now. Interesting article here washingtonpost.com - nation, world, technology and Washington area news and headlines about how the deal with D* came about.Smithsonian is 24/7 HD.
Back on topic, I have to defend Charlie and E*. Just let D* continue to add the pseudo-HD channels and watch the uproar and complaints. E* should definitely wait for some HD channels with actual HD content before launching them. Remember that the HD customers are still a small percentage of E*'s customer base.
