The udon version is probably not functioning anymore since the last patch that disabled video players in udon worlds. The prefab works by setting the UI text as a query string on the unity video player url parameter, so unity dutifully makes an http request to the url, which the server captures as a message. The vrchat devs didn't like the fact it was easy to get a player's vrchat username in udon into the query string though, so they just disabled all the video players.
