Direct TV installer is coming out in a few hours. I have Voom on 2 TVs and would like to keep Voomin on one TV and then just hook up my other tv myself at the end of the month... Can he charge extra for this..... Also I am not a wiz kid when it comes to satellite receivers and so forth so do i need to buy any additional equipment or can this all be done without directtv installer charging me extra?
