I keep seeing people mention how much cheaper an SD box would be, and I'm not sure it realy would be. Most people assume it will be cheaper, because HD boxes always cost more. The costs of prodcution are always about the same, the components are usually pretty identical, the difference has more to do with volume than anything. The reason a Dish SD box is cheaper than a Dish HD box, is:
1) They sell almost 10 times as many SD boxes as HD boxes.
2) People looking to buy an HD box will pay twice as much for the HD.
Voom could actually run cheaper by only producing one, single box, the HD one. It's not like the HD is an upgrade, it is standard for them. As for the SD tuner in the box, I'm sure it is exactly the same, in fact, I'd be willing to bet the only difference between the HD and SD boxes is the outputs. Voom only broadcasts guide data for digital OTA's, so why would they even think about instaling an analog tuner?
