@mdsharpe: For the whole site or for a specific show/series?

We do provide a high quality feed for both, the site one is not listed in our navigation but is http://channel9.msdn.com/Feeds/RSS/WMVHigh, and for a show if you hover over the 'Subscribe' link you'll get a list of the different formats, including a High Quality WMV link (http://channel9.msdn.com/Shows/This+Week+On+Channel+9/feed/wmvhigh for example)
