I could use a little help using TB for delivering an actual video, not a slideshow made from the stills.  I have made a video walk through, edited with iMovie and it now lives on YouTube.  Can anyone here tell me what I need to do to deliver the video, along with stills, to the client?  Do I copy the URL into the Custom Link window?  What is the window called 'Link Text' for?  Is that just a wind…
