I have been with Dish Network for 2 years. I have 2 receivers. One is a straight normal receiver. The other allows me to tape shows. I now want to get a 3rd receiver. That is the problem. I don't know what I should get or how to find out what each does. I saw one that basically allows two TV's on one receiver. Can anyone help me? Or send me a sight that I can read about the different types?
