comcast gave me 2 dc50x... they had to shoot me a signal for then to work so I could receive digital chamels... they send me a 3rd one but it is a dc50xu.. it works with out then shooting a singal... all 3 at no mounthly charge... if I want to buy a 4th one... dc50xu... do you think they will have to shoot a singal..? what is the dc100 used for?
thank you... richard
