directv receiver and tv? Has anyone had personal experience in replacing the stock cord to a model HR22 directv receiver(I believe it is the newest hi-def directv receiver) with an "upgraded" power cord. Was their any better picture? I am also considering replacing the cord to the tv , but unfortunately that will take some work to place an IEC connection on the set since the cord is hard wired in(non-detachable).I am willing to do it if anyone has done this or even replaced a cord to their tv with an upgraded cord if theirs was detachable. Please e mail me directly at [email protected] if if have any input on the merits of these changes.
