Hulu Error Code P-DEV320: Digital Media Player Fix

Updated: 11/29/2025

You are halfway through an episode when the video freezes, buffers, and finally crashes with: 'We're having trouble playing this. Error Code: P-DEV320.' This code stands for 'Player - Digital Media Player 320'. It specifically means the data packets from Hulu's server are reaching your house, but your device's player cannot 'unpack' them fast enough, usually due to cache bloat or a desynced app state.

Method 1: The 'Power Drain' Cycle

Smart TVs and Consoles (Xbox/PS5) never truly turn off; they just sleep. This keeps the corrupted P-DEV320 error in memory.

Step 1: Unplug

Remove the power cable from the wall.

Step 2: Hold Power

Press and hold the physical power button on the device for 15 seconds. This drains the capacitors and clears the RAM.

Step 3: Reboot

Plug it back in. This cold boot forces Hulu to re-authenticate your session.

Method 2: Lower Stream Quality (Web)

If your internet speed fluctuates, Hulu's auto-quality selector might crash the player.

Step 1: Open Settings

While a video is playing (or trying to), click the Gear Icon.

Step 2: Data Saver

Manually select Data Saver or Medium quality instead of Auto. This reduces packet size and stops P-DEV320 from triggering during bandwidth dips.

Method 3: Clear Local Storage (HTML5)

If watching on a browser, clearing just the cache isn't enough. You need to clear the HTML5 storage.

This wipes every trace of the Hulu player from your browser, forcing a fresh download of the player script.
