Maybe people who are happy w/ Voom's picture quality are coming from cable HD? My parents, and I too, watch Voom HD on 8 ft wide screens, and we can't believe how much better Voom's HD PQ is than cable's. Yes, there's mosquito noise at times, and while they don't even notice it at all, it does bother me some. But the leap from cable HD picture quality to Voom is still significant. Even my newbie parents immediately notice it.
If you get the same jump from Voom HD to Dish, well, I guess we'd be *really* happy then.
But even if cable did have better PQ, we'd never go back, due to the lack of channels. We just have a hard time watching SD very much any more. And though Voom's HD content leaves much to be desired, it still beats the hell out of anyone else in our opinion.
