Right now I have my MX-900 controlling a kitchen TV and MX-980 controlling my family room TV and the regular DirectTV remote controlling the bedroom TV. All of these TV's have a separate Sat Box.

Apparently DirectTV has this new "Genie" thing which let's me control all of my TV's with a single "box" with smaller Genie modules by each TV? Or do you have just 1 main box and 1 Genie box for up to 4 TV's?

I am guessing that the remotes will control by using RF to the central box instead of IR?

So I am guessing I would put the main box in the family room and that could still be controlled by IR via my MX-980, the kitchen would get a Genie and the MX-900 would RF a signal to a MRF-250 to control it by IR and the bedroom would use the standard RF DirectTV Remote.

Is this accurate? OR can each Genie accept IR input at each location? This would make the changeover easy.

What is the range of the RF on the MX-900 and MX-980?

If I missed something here, please correct me. Not really understanding this Genie thing correctly and the people at DirecTv are not that great at explaining it.

One DVR box, seperate boxes at each location, controlled with it's own direct tv IR remote. You access the main DVR thru the menu of each box. URC remotes will work.
Range at my house with mrf 350 , 980, 900, and kp 900 is 75- 100 feet, out in yard or detached garage. 980 has the strongest range

codeset 173 is the one you want to use
