When I click on the video on my site I go to YouTube with my video.
How to switch on the YouTube channel with my video?

Did you read this:

?

I wonder if Oleg was asking the same question I have.

After searching extensively and reading your document at www.joomlaworks.net/content/view/35/41/ I still don't find the answer to this particular question: How does one embed a YouTube CHANNEL as opposed to a single YouTube Video using the AllVideo plug-in? Or is that possible?

This is my channel embed link www.youtube.com/user/jmccunepr

I tried entering the full URL and just this segment /user/jmccunepr but neither scheme works:
{youtube}/user/jmccunepr|600|450{/youtube}

AllVideos cannot display Youtube channel.
