I watched Jim Wallis do a talk from a video link provided on sojo.net (my Firefox setup would not launch Media Player from that link, but you can play it streamed from your Windows Media Player by opening Media Player, and doing file/OpenURL, and pasting in http://www.sanc.info/video_2005/02_27_05sanctuary_300k.wmv.

There’s probably a way to provide a link that does this automatically (IE handles the link, which goes to a page that has this:

<ASX version="3.0">
<Entry>
<ref HREF="http://www.sanc.info/video_2005/02_27_05sanctuary_300k.wmv"/>
</Entry>
</ASX>
but Firefox simply stops there.

There’s probably a way to provide the correct URL to fire off the steps I listed above to manually open Media Player with the .wmv URL, but I haven’t found it by doing an intial Google search, but it’s probably out there somewhere.
