Hi there! I understand you're experiencing an issue where the Tubi app keeps pausing and repeating parts of the video two to three times before continuing, and you're also having trouble using the time bar to rewind. That does sound inconvenient. Let's try to get this sorted out.

First, just to clarify:
- Are you using the Tubi app in a web browser on your Windows 10 device, or is it a separate app installed on your machine?
- When did this issue start happening? Has it been consistent or intermittent?
- Have you tried any fixes already, like refreshing the page or restarting your device?

Meanwhile, here’s a general step-by-step approach to resolve issues like this on a Windows device with a browser:

1. Refresh and Restart
- Try refreshing the page where Tubi is playing.
- Close and reopen your browser.
- If that doesn’t help, restart your computer to clear any temporary glitches.

2. Clear Browser Cache and Cookies
- Sometimes corrupted temporary files cause playback issues.
- In your browser, go to Settings > Privacy & Security > Clear browsing data.
- Clear Cached images and files and Cookies (you can leave passwords and browsing history if you want).
- Restart the browser and try playing Tubi again.

3. Check for Browser and Windows Updates
- Make sure your browser is up to date.
- Also, apply any pending Windows updates to ensure compatibility and performance.

4. Try a Different Browser
- Since you are using a WebKit-based browser, to rule out browser-specific issues, try playing Tubi on another browser like Chrome or Firefox.

5. Reset Playback Settings
- If the time bar is not responsive, sometimes disabling browser extensions or hardware acceleration helps.
- In your browser settings, try turning off hardware acceleration and disable any ad-blockers or video-related extensions, then test again.

6. Test Internet Connection
- A slow or unstable internet connection can cause video playback to pause and repeat.
- Run a speed test and make sure your connection is stable and fast enough for streaming (at least 5 Mbps is recommended for HD streaming).

7. Reinstall the Tubi App (If Using Desktop App)
- If you happen to be using a desktop app version, uninstall and reinstall the latest version of the Tubi app to clear any corrupted files.

If after these steps you still see the repeating sections and the time bar remains unresponsive, there could be a deeper playback or DRM (Digital Rights Management) issue that we might need to investigate further.

Would you be able to try these steps and let me know what results you see? That way, I can guide you further.

Are you satisfied with this initial troubleshooting plan?
