I actually did that and tried both. It seems that I have to keep it on Auto because my TV only goes up to like 420p or something like that, so that didn’t do anything. Thanks, tho.
What Roku model # and firmware version do you have? Settings/System/About
..and how is it connected to the TV? (HDMI, Composite)
What is your TV brand/model #?
If you are using a model with Composite output to your TV, try connecting via HDMI instead to a different TV to register the TBS app, then switch it back.
(I verified this behavior on a 3910 using Composite output - does not happen with HDMI output)
Otherwise, contact TBS and Roku:
@RokuDanny-R Please pass this on to TBS/app engineering
