Stereo video encoded in a top/bottom format.
Watch at 100% zoom, because at smaller resolution grain differences cannot be seen.
The best viewing method is using shutter glasses.
Polarized screen that uses interleaving is not recommended, since grain sizes are in the order of one pixel, and the effect will disappear. 
In this case you can try viewing at 200% zoom and looking from distance.

The files were compressed using h264 codec. 
If you have problems with playing them, try installing haali media splitter (http://haali.su/mkv/) and/or ffdshow (http://ffdshow-tryout.sourceforge.net/).
