Many sites have vidcasts like this one from The Roanoke Times and these from lawrence.com. Even more news sites offer video online, but most times the video can only be watched on the web, at a computer.
Roanoke.com and a few other sites make the video available in the iPod-ready mp4 format, which lets the millions of iPod users to download the video to their mp3 players and watch it at a later time. This is a great alternative for users who don’t want to sign up for regular podcasts.
There are tons of free or nearly free programs that convert video to the mp4 format (see this list at Download.com ). There are also several online file-conversion services like Zamzar which converts uploaded videos and sends them via e-mail.
