722 Receiver, using HDMI connected to TV, as I switch between tuners (PIP), the one image is fine, but when I switch, the other picture is pure crap. Super grainy and fuzzy. I almost want to call it unwatchable. This is the first time I had this issue, so I am simply trying to find out if this is something people have seen/dealt with in the past. The strange part being that the image is fine on one tuner and crap on the other.
