How do I remove a video from my channel?

Hi All -

Probably a dumb question, but I'm a newbie here... I used Direct Publisher to build my first channel, and have used Vimeo to host my content.  In testing I added a couple of sample videos.  They now appear on my channel, along with the ones I want to keep.  How do I remove them from the Channel?  I am not a programmer, and don't see an option in the Direct Publisher steps.

Thanks in advance for any guidance.
