A while ago I found my old copy of Are You Afraid of the Dark: The Tale of Orpheo's Curse.
and found some notes I made on it last year.
It turned out that this game had fmv(stored in umv) files, and after contacting Multimedia Mike,
I was lucky enough to have him post a blog post about it over at http://multimedia.cx/eggs/orpheos-umv-format/
and even created a wiki page for the format
Now I was reading the comments and noticed that someone had actually taken a look at it, but wanted to know what the videos looked like originally
so I captured one, the actual video(umv) starts at 0:20
So this is a little thank you to the person who started looking at the format, and Mike for making the effort to post the article in the first place.
