Why am I getting this error from my show.js.erb file?

I have this code in my profile show view:

<div id='main_profile_column'>
  <div id="video_div">  
    <% @videos.each do |video| %>   
      <%= render 'videos/video', :video => video %>
    <% end %>
  </div>
         <%= paginate @videos %>
</div>

and I'm using a show.js.erb file to render the video partial in order to implement AJAX pagination. I have this in my show.js.erb file:

$("#video_div").html("<%= escape_javascript(render("videos/video")) %>");

How this code gives me this error:

GET http://localhost:3000/profiles/45?page=2&_=1302255080024 500 (Internal Server Error)

What code should I be putting in the .js.erb file?

Here's the error from the log:

Is your @videos variable setup correctly in your controller/action?

Try this one:

$("#video_div").html("<%= escape_javascript(render(:partial => "videos/video", :collection => @videos)) %>");
