I want to show videos from Youtube with custom settings from the Youtube Player Tools parameters.

I use K2.

I realise I could simply create the iframe embed code and paste it into the appropriate K2 tab however...

We create sites for conferences and we upload lots of video during the conference
and
We provide sites with access to the backend for inexperienced users.

It would therefore be convenient if we could doctor the appropriate file in AllVideos to include the appropriate parameters as standard thus allowing us and clients to "Use the online video service" rather than the "Embed Code" tab.

Can you tell me where to find the file I need to ammend

Hi. The file that is generating the youtube code is located at /plugins/content/jw_allvideos/includes/sources.php.
