Ok so my Directv setup of a HR34 and 3 HD Receivers is scheduled to be installed this Saturday afternoon. I live in a 2 story house.My main concern is that I have a previous DTV dish sitting on my roof from when my house was being rented out 4 years ago and some wiring is still on top of my roof.I will say that I was not happy when I saw this old install & setup and know the contractor who installed that setup did a piss poor job overall. Now what I'm trying to avoid on this new DTV install is that the installer telling me "Your going to need a custom install" that will require additional $$$.I asked the sales rep about this and she said "don't worry your install will be free and the installer will remove your old DTV setup before installing the new DTV equipment". I'm really weary about what the sales rep said and kind of have a gut feeling that the DTV installer is going to tell me I need a custom install and will be required to pay additional costs. Also what other advice can you guys offer me and what to look out for during the install? The HR34 will be installed in my master bedroom which has my 40" Sony Bravia TV, PS3, and my AT&T DSL U-Verse 2WIRE gateway.2 other HD Receivers will be installed in 2 other rooms on the 2nd floor of my house and the 3rd HD receiver will be installed in my downstairs family room.
