Sorry, but if there’s a video, we can’t find it
The most common reason for receiving a “Sorry, but if there’s a video, we can’t find it” error is that the website isn’t supported by the Plex It! bookmarklet.

However, not all unsupported sites will use these common methods and so videos on such sites may not be discovered.
