I am getting DISH installed next Saturday, I am getting the 622 dual tuner HD DVR, 1 311 & 1 HD 211 receiver. I have 2 questions how exactely does the 2 tuner receiver change channels from another room like my basement or are there limitations on how far or which room it needs to be in & also will there be only 1 cable coming into my house then run from a multi switch at that point to the other receivers? I want to have all the cables in one area when the installer gets here as i currently have comcast cable HD which i love but the bill keeps getting higher & higher. I have a cable going up to where my voom & direct sat. used to be i just need to redo some of the cables to get them all to point a Thanks for any info
