On YouTube TV video on demand (VOD) the screen will go black after a block of commercials. Unfortunately, the show or movie will not return. This happens on all my Roku devices.
An annoying workaround is once the screen goes to black, scroll down with the remote and select a video quality that is different from the one you’re currently on. Example: if you’re on 1080p, select 720p. Then return to the original video quality. The show or movie will continue.
This has worked on my Roku 3 and Sharp Roku TV. Hopefully Roku fixes this problem.
