When I first set up my 722k,I thought that my receiver was set up for 1080i,but it turned out that it was set for 480p(I have my 722k hooked up with HDMI cables). What I mean is that the tech set it up to broadcast in 1080i,but the receiver was broadcasting in 480p even though the receiver said it was set for 1080i. First off,what does your TV say that the receiver is broadcasting in? What I did to make sure that my receiver was broadcasting in 1080i was I changed the resolution to 720p,confirmed that that was what I wanted,checked with my TV to make sure that that was what I was getting,then I went through the whole procedure again,changing it (back) to 1080i,& then checking with my TV to make sure that yes,it was broadcasting in 1080i.
