Advertisements I have a brand new OTR Roamio. Hooked it up via HDMI to Yamaha receiver. I have the yamaha set to STEREO mode as I only use 2 speakers. My OTA TV channels, via the HD antenna, plays fine and the audio comes out in stereo. When I move to the Plex, Hulu, or Netflix apps they start to load and then the Yamaha receiver switches automatically to surround sound and locks up not, allowing me to switch it to stereo. I can hear 2 of the 7 channels witch is not how it should be working. Again, regular TV is fine via Tivo but the apps are causing this switch. Any settings I can adjust either generally in the Tivo unit or specifically in the apps them selves? Also, when I run these apps form Apple TV, all is fine. No switching to surround sound. Any help would be appreciated.
