No problem.
Ok so download the file attached, go into modules and import it from the bottom page. What you will want to do after that is edit it in your adminCP. Login to your AdminCP and go to Appearance>Templates and search for 'PortalYouTube' and open it up
This will allow you to edit the template/module directly from your adminCP without having to download it and edit it in notepad everytime. All you need to do is change the title to whatever you want and leave the youtube code intact. To edit the YouTube video shown do the following...
In this example you will see the link '
http://www.youtube.com/embed/CXTyV3u6Mkc' in the template, the only part you need to change is the 'CXTyV3u6Mkc' which is the youtube video ID. You will notice a similar code in every YouTube Video, simply change it as you wish. And then save it and place it on your portal page via the module settings... I used 'center' placement for mine with a sort ID of '0' which puts it up the very top, up to you where it looks best. Let me know if you have any issues.
