Potential causes for Hulu errors could include corrupted cache data on your device, temporary server downtime for maintenance, an unstable internet connection causing TCP or IP inconsistency, and an outdated browser lacking support for streaming protocols.

Key Takeaways

  • Hulu Error Code DRMCDM78 is displayed as “Error playing video” and prevents content streaming.
  • Causes include cache corruption, server issues, unstable internet, and outdated browsers.
  • Solutions involve clearing the cache, updating browsers, restarting or rebooting the router, and contacting Hulu Support.

Clear The Cache Data

Cache data is sometimes useful in the sense that it helps to restore your previous data. I’ve used cache data to restore previous sessions, too, but excess cache can cause streaming errors like Hulu’s DRMCDM78. WoeIsTravis on Reddit got Hulu back to streaming by clearing the cache. Clearing the cache does not affect the performance of your browser; however, you will be logged out from the accounts whose data was saved as your cache data in the browser.

Update your Browser

You have verified that the problem is not from the Hulu server’s end and is not linked to the cache. Now, the next thing you can do is check for browser updates. There is a high chance that your browser is not up to date and lacks some important updates to enable support for streaming protocols. Follow the below-mentioned steps to update your browser.

Chrome (Windows/MacOS)

  1. Open Chrome and click on the three-dot icon present on the top-hand side of your screen.
  2. Go to “Help”→”About Google Chrome”.
  3. A short scan will happen to find any updates. If any new update is available, it will display after the scan.

  2. When you are prompted to confirm the operation, press “Y”.

Firefox (Windows/MacOS)

Open the firefox→action icon at the top right corner→”Help”→”About Firefox”→Restart and update Firefox(if an update is available).
