584 lectures are viewable on the internet as Microsoft NetShow programs, both live and on-demand. The plan is to encode a stream with URLs pointing to lecture slides so that the slides will be synchronized with the talk.
You may also be interested in our selection of past graduate-level courses and CSE Colloquia available for on-demand viewing.
To view a Netshow program, install the free Windows Media Player , and then at class time, you can view the lecture using:
Links to the on-demand lectures will be posted in the main Lectures page on the day following the lecture.

One misleading error commonly reported by the NetShow client is Bad or missing channel URL. One way to get this error is to leave your Media Player client configured to use a non-existent proxy. In the Media Player, go to View menu->Options->Advanced tab->Windows Media, and click "change" then select "no proxy" and reload.
The NetShow server is capable of delivering a stream with HTTP. If you have trouble receiving a NetShow program through a firewall, verify that your player is configured to use the HTTP stream. The Windows media player settings are under View menu->Options->Advanced tab->Windows Media. HTTP enabled is the default setting.
Netshow may optinally use multicast delivery. To receive multicast, you must have multicast-enabled routing on your network. If you're not sure whether this is available to you, ask your network administrator. Netshow will normally try multicast first if you have enabled it in your client. If it is not available, it will roll over to unicast. If you can use the multicast, we prefer that you do so.
It has been observed that Media Player clients receiving multicast may occasionally lose track of the stream, and get stuck once in awhile. If this happens to you, try using unicast. To force the client to use unicast, go to View menu->Options->Advanced tab->Windows Media, click 'change' and disable multicast. Quit the Media Player, and restart it.
