Regarding the router comment, there was some confusion about the intention of it's "nuts" comment about ad blockers. I know routers can have ad blocking. It's simply nuts to use the router for that function because some pages you would want to allow ads and some not. A router as that tool would make it cumbersome and a tool for the lazy.
The fact that Paramount sometimes has shows that work on a Roku and sometimes not, with the Ads, tells me it is not the router which would be a constant on situation. As an example I watched a show a week ago that wouldn't load on Sunday, but the same show on the following Tuesday would load. If the router was the culprit, it would never load.
Pandora used to have a similar problem for months and I know that is finally resolved. Not sure why it takes so long to resolve these issues.
