I have not tried this yet, but it's worth a shot. Just tossing out ideas. Let me know if it works.

In user.tpl you'll find code relating to their URL which looks something like this:

Code:
{if $user_info.website ne ""}
Website:{$user_info.website}
{/if}
You might have to stick that into the appropriate place on view_video.tpl?

For the photo, all it says in user.tpl is

Code:
[img]{$photo_url}[/img]
Not sure if just poking that into view_video.tpl will work or not.
