Dish is great. Having use both, I prefer my VIP 622 to tivo. I’ve had it for just over 2 years now, at 2 seperate places. When I had it at school, going back to TW HD sucked enough that I got my parents to switch over the course of a 5 week break.
If someone hooks you up with a Club DISH card, you can get free installation WITHOUT the contract. I have them too, but im only 3rd in line. If you don’t like it, cancel, return your shit, and go back to cable. You have nothing to lose. That said, I guarantee that if you go Dish you won’t go back. Picture quality, even on SD channels, is much better than Time Warner on even the shittiest TV. You have DVR on all of your TV’s, instead of each room being extra. In terms of signal problems in bad weather, if you have an installer that knows his shit (I had a board member do mine, highly recommended) then they are a non-issue.
