I have a Direct TV HD DVR receiver and an LG 42" 1080I HDTV. I bought an off air anttena that is supposed to pick up local HD channels. Last night I go to plug it into my recevier and there is no input for an off air anttena. My brother-in law's receiver does have one as we were watching channel 8 in HD yesterday. I call Direct TV last night and the tech tells me that some receivers have this input and some don't. I ask what I can do at this point to get local channels in HD and he says he has to put me on hold. Then after he hasn't come back after 10 minutes I just hung up. I bought this receiver from Best Buy so I assume that it can't be exchanged for one that has the off air input but I haven't yet gone there to ask. Has anyone else run into this problem? I have tried just plugging the anttena into the anttena input on the TV but I barely get any reception let alone an HD picture. Any help from you tech gurus would be appreciated.
