New install, and a number of questions?....Please help

Thank You in advance.  I'm sure a number of my questions have been answered on a number of other posts, but here goes.  I got an upgrade today(which I am not happy with.  Whole nother story. didn't care for the install guy.)  I previously had two recievers on HD DVR and one standard DVR.  I upgraded and added another HD DVR and a HD reviever and got rid of the standard DVR, also added whole home DVR.  I have a two story house.  I had the HD DVR downstairs and the standard DVR upstairs.  I was able control the other tvs upstairs from the standard DVR with a RF modulator.  Install guy said that I cant use splitters with the new system.  Can this be fixed so that I can control the other upstairs tv's?  Would be a major disapointment if I could not.  So he swapped out the standard DVR and added a HD DVR.  I am able to get video but no audio in the other rooms.  Is there a different type of splitter that I can use?  Next question.  I had a standard HD reviever added to one of the room downstairs and that was fine, but now I can not get the Whole home DVR to work with any of the recievers.  Install guy left and never said anything about it, so I assumed everything was fine.  I asked him several times if I was going to have Whole home DVR service.  He stated that I would.  He seemed like he was in a hurry to get out the door.  I had a slim line dish which he changed and added a single wire multiswitch. Next question was I asked him about a Cinema plus kit so that I could watch shows from the DVR on the PC.  He stated that he had one in his truck, but asked if I was sure that I wanted it because he stated that Directv will charge we a fee every month and that it would be like I had another reciever.  Is this true?  I'm sure I have more questions but that is all I can think of at the moment.  again thank you..
