Tom, Thanks for your speedy response. I want to make sure we are on the same page. I am using the video template, not plain text where one can import a video. I used the xerte "uploader" to upload my short video clip (mp4) and then brought it into the form where you're supposed to register the video. There is no iframe involved. Is the 404 error because I am missing a xerte file in my installation? If I try to use a url address to load the video, xerte responds that it can't use that as a source.
Thanks.
