We currently have cable thru our phone company. My parents, on the other hand, have DirectTV. I've never had Direct TV so in order to learn more I visit Blogtelevision.com. You can learn more and order straight from their website. You can check out current offers, learn more about HD tv, and things like the NFL Sunday Ticket- which I know my boys would LOVE. It's a great explanatory site. I learned more about the DVR- which now I can't imagine NOT having. I also was able to look thru the different programming packages to find the best fit.
If you have more questions about Directv you can also call their toll free number. It's definitely a convenient site to have to answer questions and order the great service for your tv viewing.
