So how does that work. -- do you watch the non-HD channels on the HD TV? -- does your TV somehow make an adjustment? I think I follow your question. Yes, you can watch the non-HD channels on the HD TV. I contacted customer service a few weeks ago about a similar issue. I'm getting my HD TV in two weeks and wanted to know how that would work with my current receiver and such. I'm going to stick with my current setup and see how it looks before I upgrade. Unlike many others, I'm not that gung-ho over HD. If you want to receive HD programming, you have to order a HD box from DirecTV. If you stick with your basic receiver, you will not be able to get their HD programming. I don't know if it's only a receiver change, but for some reason I thought my parents also had a new dish installed when they went HD.
