Having same issue. For me it seems to randomly shrink to top left small view. It does it when watching On-Demand for me. Only work around I've found is go to home then library and find the show and select the episode and click it. It buffers for a few seconds and correctly shows. Then it shrinks again and I have to go to home and repeat those steps and sometimes it doesn't fix. This is pissing me off. Roku or YoutubeTv needs to fix this.
