Thanks for reaching out to report the issue. A few questions here:
1. What film were you watching when the issue occurred?
2. Approximately what time did the issue occur (and which timezone)?
3. Have you observed this issue on any other channels?
Please feel free to send me a private message with your Roku device serial number from Settings>System>About, along with any extra details you can recall. I'll help pass along this feedback to the channel provider and request they help take a closer look. I'd also recommend following up with them directly to share your report, and request any additional assistance they may be able to offer.
Thanks,
Tanner
