Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
It sounds like the same issue I am having. Only Amazon Prime isn’t accessible from my Roku device. I can get it on my other smart TVs. I was watching a show on Prime, changed to watch Hulu and went back to Prime 1/2 hour later and was unable to access Prime.
Can't believe it was as simple as setting the Roku display resolution to match my TV. Roku was set for 1080p and my TV is only 720p. Ever since I changed it the only buffering I've seen over 5 -6 days (2-3 movies, many episodes of same shows I had issues with) is at the very beginning of a video. Which is usually during the preview that Prime queues up. Absolutely no buffering beyond that and no audio-video out of sync.
Hope it's this easy for the rest of you.
This worked for me. I changed the resolution of my Roku to 720p. It was 1080p earlier. But definitely not the ideal solution. This would mean that the content in other roku channels would be lower than it could be. I have keep changing them when I use Prime vs other apps.
Exact same problem here in Phoenix. Streaming fine on all channels except Prime Video. It buffers at the beginning of the video and then when it starts playing smoothly the sound almost always doesn't match the video and I have to do quick (short) rewinds until the lips match the voice. Then there is intermittent buffering during playback and I often get that black box telling me to exit and check my connection which I have done and the result is always OK. Now when I get that message I just wait and eventually it starts again. I've been putting up with this a long time, I'm not sure why, but finally it occurred to me that I shouldn't because I'm paying cash money for Prime and it onlyhappens on Prime. I'm going to try uninstall, reinstall, restart but I'm not optimistic. And I have a 1080 TV and shouldn't have to make it 720 just for Prime Video. And I'm not going to hunt for hours on Amazon looking for a phone number for Video support. They are excellent at hiding customer service numbers and as usual it sounds like Amazon is blaming Roku and vice-versa anyways. So I hope somebody finds a fix soon. There are a couple of shows I really like on that channel
Same problem- weird in only for certain shows on prime (where it stutters)..tried changing resolution down to 720 - didnt fix. Dont understand why some channels work and others dont..thought it was cause prime offer some in 4k but it happens across shows that aren't offered in 4k.
