Playing a Youtube video on Coppermine

[THudson]

I've read somewhere that it should be possible to play videos on Coppermine by linking it to the youtube URL.
The post I saw seemed to suggest that you had to modify some files. I'm not confident about that, so has anyone written a plugin to do this?

Thanks for that, but installed plugin selected formats as described in the post, but all I get is the representation of the document thumbnail.
If I click on this thumbnail, all I get is the text of the URL in a new window?
What am I doing wrong, as I followed the instructions to the letter?
