I'd very much appreciate the ability to outright disable video players in worlds as a client setting. This was in part due to a video player I found that clearly did not intend to have its address changed manually by other players, have its address changed to an incredibly loud screamer.
I understand that the ability to disable a video player is usually up to the world maker's discretion, but I shouldn't have to risk an anxiety attack on a per-world basis if they didn't implement such a feature, or forget to lock the video address.
Additionally, I've had issues with video players severely impacting performance in instances with many users, as well as using unnecessary bandwidth.
