during my lunch I picked up the receiver so I need you help in quickly setting it up tonight. Is there any common mistakes I should be aware of so I don't repeat them? Or will this be a simple swapping of boxes between the SATHD 100 and the SAT A55 I currently have? Can't wait to get home and see HDTV in my own living room. Now I will have so much more to be thankful for on Thursday.
