Not sure what the real answers are, everyone tells me something different. I bought a new 42" Samsung LCD HDTV. DirecTV gives me a good deal on the HR10-250 and I ask if I can go to a local store to buy it. They say sure. I go to 6th Avenue Electronics, and the salesman seems very knowledgeable. He says I only need a 3LNB dish. My house is in West Virginia. DirecTV says I need a 5LNB dish for DC locals because of MPEG 4. The salesman says MPEG 4 won't be available for a long time. I call DirecTV while at the store and they say I need the 5LNB now in order to receive DC locals. Then the salesman says their installer may be able to get a 5LNB dish in a week, maybe more. But I can get a 3LNB dish right now. What to do? Also, the salesman said an HDMI connection from the Tivo to the TV is all I need for the best picture, but the cable is $125. $125!?! He says I only need one cable even though I have two tuners of course, with the Tivo. True? Thanks.
