Everything connected via HDMI. When I put the Bell receiver on a non HD channel on the front of the AVR it shows the speakers including SBR/SBL surround back left/right. When I change it to an HD channel the SBL and SBR speakers disappear from the display on the AVR. It also switches from (non HD) ALL Ch Stereo to Dolby Digital when it switches to HD channels.
