Hi! I understand you're able to watch some episodes on the Viki app on your Roku TV, but trying to play two specific episodes causes the app to kick you back to the home screen. Thanks for sharing that detail—it helps narrow down the issue a lot.

Let me suggest a few steps to try and get this sorted out:

1. Restart your Roku TV:
Sometimes temporary glitches cause crashes. Try restarting your Roku TV by going to Settings > System > Power > System restart and confirm the restart. This clears temporary cache that might be corrupted.

2. Clear the Viki app cache/data:
Roku doesn't have a direct way to clear cache per app, but uninstalling and reinstalling the Viki app can help clear any corrupted files affecting those episodes. Here's how:
- Go to the Viki channel, press the Options button on your remote (the one with the * star *), and select Remove channel.
- Then, reinstall it by going to Streaming Channels > Search Channels, type Viki, and add it back.
- Sign back into your account and try those episodes again.

3. Check for app updates:
Roku updates apps periodically. After reinstalling, the newest version should install, which might have fixes for issues causing crashes on specific episodes.

4. Test other episodes and the "problem" episodes later:
Sometimes the problem is with the content itself or streaming servers. If the issue persists even after reinstalling, it could be a problem on Viki’s end affecting those episodes. In that case, keeping an eye on Viki’s support channels for any ongoing issues would be good.

If you’ve already tried these or want me to guide you through any step, just let me know! Also, if any error messages pop up before the crash, sharing them would help.

Are you okay to start with restarting the Roku TV and reinstalling the app? I’m here to walk you through it.
