Thanks Guys,
That makes perfect sense. It would make even more sense if it went to the bedroom. I can confirm that the rear connector goes to the entertainment center.
One reason that Directv won't work on a particular tv is if you are trying to send the signal from the receiver to the tv on either the tv's channel 3 or 4 and your tv has a digital tuner. The signal my Huges receiver puts out is analog.
