Star button won't access picture mode an longer.
I had a Streambar Pro connected to my Roku TV via HDMI port. I unplugged the Streambar Pro speaker from my Roku TV. I paired my remote to the Roku TV (not the Streambar Pro), started a show, pressed the star button (*) on my remote and the picture settings appeared. I then reattached the Streambar Pro and found that the picture settings came back using the *.
When you have a Streambar attached to a Roku TV things can get confusing. You might want to use a different wallpaper on the TV vs. the Streambar so you know which one you're currently viewing. You always need to use the TV's remote to access picture settings, so if you were viewing the Streambar and using its remote, the * would bring up settings applicable to the Streambar, not the TV.
