If I'm using a VR headset, are there any specific VR settings that could be causing video errors in the Popcorn Palace?

While unlikely to be the direct cause, certain VR settings can indirectly influence video playback. Ensure your render scale isn't set excessively high, as this can impact overall performance. Also, check your VR drivers and client are up-to-date. If you are using a particularly resource-intensive setting in VRChat, temporarily lower them to see if it resolves the video error.
