I have Dish 500 with a 2700 and 4700 receiver. I want a DVR and new TV. I purchased a large Mitsubishi TV that needs a high definition satellite receiver. The salesman recommended the Dish 921 instead of their upgraded TV with DVR. I called Dish (need I mention what that is like!?) and they said they do not sell the Dish DVR 921 but they gave me some numbers to call. I called VMC and they sell it but can't install it. The TV dealer said I also need an antenna on the house to get HD on local stations. Dish doesn't install or sell the antennas and neither does VMC. I have no confidence in my ability to make these products work together, especially after reading the 921 thread. I do not know what it means to have to run two cables to the 921, etc. I would like to be sure that I am buying something that makes sense. I would also like to find someone that can make this all work together. Any ideas? Thank you!
