I would like to get MRV & VOD services activated. I have one each: HR22/100, HR23/700 & two HR 23/600 boxes installed and working, they are connected to a SWM. Am I understanding that if I can get one ethernet cable hooked up between any one of the DirecTV boxes and my AT&T wireless PC wi-fi router that is all I need for the networking connection for MRV & VOD? Then I will need one DECA device on each DirecTV box, correct? Do I need any additional hardware for VOD/MRV service or otherwise? Will there be any conflict between my PC network and the DirecTV network after this install, such as slowing down my 3mbps internet connection? Should I get the hardware/kits I need from DirecTV and install them myself or should I let DirecTV install the hardware? I have technician skills. Is there any cost benefit to buying the hardware eleswhere and installing it myself? Am I overlooking anything else as part of this project? Thank you.
