the best way to find templates is to use google to search.
What would you call this then? Pop-up video preview window thing?
I couldn't use your link but I think i have an idea about what you want....
try searching for "video lightbox"
Light & Shadowboxes aren't what I'm looking for as they are too intrusive. They require a click to activate, then take over your entire window, and you have to click again to dismiss.
Don't know why Adobe Forums isn't showing the video.
Look at this link:
It's a pop-up video preview that doesn't require any clicks. Just mouse over. I'm impressed that the video just takes an instant to load.
