Pressing the interactive button beside a lecture title takes you to the interactive video, viewable in any desktop browser with Flash Player, that lets you zoom in and out on anything of interest (such as blackboard writing). Pressing the static button takes you to a downloadable video that can be played on any desktop or mobile player that supports the Ogg Theora video format (Firefox and Chrome have this support built in), but without the zooming in/out ability that helps make blackboard writing legible.

The info (and, in some cases, slides) links take you to a web page with information and downloadable slides. If there is no slides link, there may still be downloadable slides available from within the info page. Please note that, during our transition to a new web site, many of these links will still take you to the old site.

Some Flash Player versions have a bug that causes garbled video in the interactive version. If this happens, right-click on the video, choose "Settings" and then the (left-most) button for Flash Player's "display" settings, where you should try turning off hardware acceleration.
