CBS (ended 2008)
No special software required to view them. View the episodes right away.
Many other TV shows available @ http://www.fancast.com/full_episodes
Not sure if everyone can view these or not. It's provided by Comcast .
Season 1 eps are also available for free on Joost. Don't know if they are viewable by non-US resident, though. But you could give a try.
Thanks for the Fancast link. By browsing the shows available there, I realized that Mayor Green was also Major Dad!!! I used to love this show when I was younger
