Hi everybody. I have the following problem:
I have inserted a youtube videoplaylist in a page of my joomla website (still under construction) using All videos:  lnx.waterwind.it/j25/foto/videoreport.html . It is the last box of the page. In this page, everything is working good.
I have inserted another youtube playlist using All videos (and using the same procedure) in another page: lnx.waterwind.it/j25/shopping/nuove-uscite.html
In this second page, the playlist doesn't work properly. I mean the symbol in the left-high corner of the box doesn't allow to display all the videos available in the playlist as usual, and I have noticed that, instead of the name of the playlist, in the top of the video box, you can only read "playlist".
To have the playlist working properly, I had to insert it using the usual youtube embedding code (see two last boxes of the page), but so the video boxes are not responsive, and I'm not satisfied.
Where is the problem? I'm going crazy!
Please help me. Thanks

In the URL of your second video playlist page you have a space which causes your video playlist not to work.

Your URL should be:
www.youtube.com/embed/TN_ExhPDKbM?list=PLjggdf0hyRcpaK8dLrD1_fWLpAdQYfeZQ&rel=0&fs=1&wmode=transparent

rather than this:
www.youtube.com/embed/TN_ExhPDKbM?list=PLjggdf0hyRcpaK8dLrD1_fWLpAdQYfeZQ &rel=0&fs=1&wmode=transparent

Thank for your kind reply. Now it works. I used the code suggested by youtube, which not include the last part you added (&rel=0&fs=1&wmode=transparent). Now that I added this part, everything is ok. Youtube should suggest better codes....

Please add to your documentation instructions on how to add YouTube playlists... I've needed these a couple times now, and I keep having to search for this thread since it is not listed in your documentation.

It boggles my mind that you all work so hard to improve your tools capabilities; however, you fail to update your site documentation to point out the updates.

You just have to keep in mind to not bring any spaces while copying/pasting the link from youtube.
That is the trick.
