Hey all. I had the CBS All Access app on my ROKU Ultra, yes, it is in DD 2.0 only , we watch a lot of CBS programming. This is inexcusable in 2018! They experimented a bit with 5.1, I said hey, they finally got it right. Not any more, the picture started buffering, and lowering it's quality until they finally downgraded again to 2.0, and the picture improved again. I found out that CBS All Access is available through Amazon Prime, with not the depth of archived programming, but it is all in 5.1! At first, I was concerned that it was a 2.0 program with a 5.1 stream. Not so, listening a bit, it is in true discreet 5.1, and the picture quality, in 1080p, looks better than from my Xfinity X1. Give it a try.
