Embedded videos - copyright issues?

[Chris71]

Hi,

I don't know if this is the best section to ask, but...

Does anyone know if you need to seek copyright permission from the original owner to embed a publicly available video (from YouTube or the like) into your web page?

The fact these video hosting sites all have a big 'embed' button, as well as the fact the video actually remains hosted on the original site and played remotely on yours, suggests that it should be okay, but I wondered if anyone knew the definitive answer.

Cheers,

Chris
