Roku streaming stick works fine on TV. When plugged into Yamaha AVR HDMI port all Roku menus are visible on TV. Looks like it's working fine until you try to actually watch any show or movie. Does not seem to advance to buffering spinner. Roku was registered while attached directly to Bravia TV. Could this be a registration issue? The older Yamaha AVR and Bravia do not seem to be ARC compliant. Currently running Stick in TV and using optical cable to Yamaha but not the optimal situation and need an answer for future. The placement of Roku stick with regard to wifi signal is only 18" compared to back of AVR vs. Back of TV so I don't think it's a bandwidth issue. Finally, When attached to AVR the "clicks" from the Roku remote can also be heard through home theatre, it just won't play any shows, period.
