Hi all, long time lurker, first time poster. I have the Onkyo 507 receiver. My PS3 and cable box are hooked in with hdmi and hdmi is outputted to a Samsung un46b6000. My problem is in the cable part. When I switch channels on the cable box, the receiver takes forever to pass the signal to the tv. The display on the receiver shows it jumping from output type to output type.(i.e. plII movie to direct to something else to something else before it settles on one of them) I would like to know if maybe I have a setting messed up on the 507. I have changed cable boxes with no improvement. Maybe someone knows of a setting on the cable box that is messed up. (TW) Thanks for any advice.
