Hi: i have a 211HD and a analog receiver with 2 tuners in other room which has chan 3 and chan 21 and i want to upgrade this one to HD,but i want to have also the 2 tuner with same chan 21 because i want to be able to use it in same way that i'm using now with chan tv 2 with chan 21, that is very handy because i can send the signal from the living room from the 211 to other tv's chan 3 and the tv 2 chan 21,
