Mathematisches Institut Georg-August-Universität Göttingen

Clay Mathematics Institute Summer School 2006 on "Arithmetic geometry" Recorded Lessons

The lesson movies are avi-files, the video compressed with XviD-Codec.
Each movie is about 450 MB or less (except where stated).
Some browser-plugins may handle this as a streaming format but in general this is no streaming media so to be sure You need to download the whole file.

Windows:	Please download the latest XviD-Codec from www.koepi.org/xvid.shtml
MacOS X:	by default the QuickTime-plugin doesn't know how to handle the XviD-format. There are two possibilities to use XviD with Quicktime: Download and install the binary XviD_Component for Quicktime from n.ethz.ch/student/naegelic/download Download and install the DivX-codec and the XviD-delegate component for Mac OS as described here: www.xvidmovies.com/mac/
Linux:	Please consult Your package-manager to download the lates XviD-package Usually the codec gets installed with any media player.
