Now I have my DVR's auto tune to HD turned off and when I turn to the channel that I have always turned to for BBC America, in my case 166, I get the BBC World News Channel instead. Now If I turn to the HD channel for BBC America, in my case 733, I get BBC America. Also, if I were to have my DVR's auto tune to HD turned on I get BBC America on 166. Does anyone have an idea as to what might be going on?
