This module was extremely simple to set up. I had to make a small template modification to get it to do what I wanted. I added m4v as one of the supported filetypes in the quicktime template, and now I can embed m4v (H.264) videos [hidef from our camcorder] right in our joomla site.

I can't comment on the support, because I didn't need any. The doc was enough to guide me in making the template mod. [That's a good thing.]

A+.
