Start playing a video and make the mistake of tabbing away and then tabbing back to that tab? "An error has occurred".

Start playing a video, and pause it for any reason, then come back and try to unpause it? "An error has occurred".

Start playing a video and try to skip forward or back within the video using the playback slider? "An error has occurred".

Start playing a video and let it play some random amount of time? "An error has occurred".

Try to start playing certain random videos? "An error has occurred".
