Not sure on the whole "Direct TV satellite" part, but the best info I could give, is to compare it to my system. I have CD player, DVD, digital box, amp and video. The video is basically connected in between the aerial and the TV. So the aerial from wherever the TV signal is coming from goes into the back of the video, and then another cable (same type cable as the aerial) goes from the video to the TV.
Not sure if that will help, apologies if it doesn't.
Thanks,Alex, we'll try it! Nathan, we do have extra inputs on the receiver. Sorry it took me so long to get back to you. We've been really busy...the garage door opener went out yesterday and had to replace that.
