Without seeing the context of the code above, I would guess you would
need to save() the video for it to show up, but of course that would
probably not work in your situation either.
A quick google search shows the following snippet should do what you
want: http://www.djangosnippets.org/snippets/1350/
{% for video in video_list %}
{% if video.key in favorites.keys %}
... offer to remove
{% endif %}
{% endfor %}
