podcasts and video blogs for Linux

 PenguinTV has a light-weight but powerful interface that shows you what you
 need to know, and hides what you don't. You can immediately see what you've
 watched, what's available to view, and which media are downloading. You
 don't have to worry about where files are stored, what their names are, or
 what format they are in. Rather than try to reinvent the wheel by coding its
 own media player, PenguinTV launches the media player of your choice to view
 your downloads.
