Google Video as you know lets you download the video to your system.
So the file downloaded(*.gvb) is not the video file but the URl locator to the actual media file which Google Player (VLC) use to download the actual *.gvi ( actually avi ) file.
This file you can play on any system any media player provided that they have required codec. But google wont let the Windows Media Player play this file (healthy competition huh)
So they changed the fourcc code of the avi sorry gvi to some junk so that WMP wont play it but as other player have their own parser for reading the header of the media file they just ignore that code and not worry about it......................................
Google knows it of course so they became evil and dint let Windows users with WMP see their vids. Is it fair to say Google is no evil any more
