need help identifying intro music

need help identifying the intro music to this random video i ran by.
I'm not even sure which language the lyrics are in, but I'd really like to know .

It sounds a lot like "Carmina Burana" by Carl Orff (http://www.youtube.com/watch?v=BNWpZ-Y_KvU), even though it's not the same composition, but it might well by something else by Carl Orff. The lyrics in "Carmina Burana" are in Latin, which sounds like the language in your song, too, and that characteristic sound comes from the male and female singers singing in octave harmony against driving classical music in a minor key.

Skip the next two paragraphs if you are not interested in searches.

O.K. Just so people understand the difficulty, this request served as a benchmark for me. Notwithstanding simnia's, as always, excellent and informative comment, i looked at this one as one more production music clip. The search engine used indexes about 120 'libraries' (including 2 popular ones, Audiomachine and X-Ray Dog). The keyword 'choir' alone returned 7 400 results and 'choral' another 3200. Sticking with just 'choir' and limiting duration from 50 to 59 seconds it returned a manageable 175 hits. I found the clip at position 153. Excluding multiple instances or variants of identical titles, i guess i listened to a few seconds of 50 or 60 of those titles.
I was very lucky. There are many more libraries out there... (the very 'hot' 2 Steps From Hell was not in the search). Also the producers of the video could have used an extract from a longer piece, extending the search to the possible 7 400 limit and no guaranteed result. So luck is a big factor...

The song is:

X-Ray Dog - Propero Antiquitas Remix
CD 14 (Dog Eat Dog 1) Track 18 (2005)
Composer: M. Griskey
Description: Slow Building To Driving Double-time Action Tribal Drums With Raging Gothic Choir Orchestra Themes Hits And FX. Fast

P.S. No worry, i will not search for the 15 sec intro that precedes. No Way!
P.P.S. I will not identify the search engine (easy enough with Google results)
P.P.P.S. For news and more

I'm blown away by your efforts and by new technology. Modern technology is threatening to make personal expertise obsolete. If anybody wants to collaborate on a better music search engine, like using Semantic Web technology, please let me know. I'm a computer programmer looking for any paying job. Thanks for the kind comments, also.

The OP is not coming back is he? So it goes...

@simnia,
I'm afraid I'm a bit too verbose...The effort while not insignificant (1 hr more or less) was in time spent. The rest is data filtering (thinning) a database as a user, none of the complex relationships of the expertise needed to create it.

The point i clumsily tried, am still trying to make about databases and their necessity, IS made here:

Interesting stuff you may already know...

P.S. not nearly as lucky with Error404's post (maybe it's the online name... )

the first 15 sec thing is from some movie, but which ? I did hear it somewhere. I will try ...
