I love listening to audiobooks, I love watching TV series.
And thus I love podcasts.
All links named podcast are direct podcast feed links.

FOX has a couple of good ones ( usually a recap, sometimes extra's)

* 24 podcast
* Bones podcast
* House podcast
* Prison Break podcast

As well as all extra's in one podcast called All Acces with all the interviews with cast and crew and so on.

The one for Killer Instinct (which sadly got cancelled) was extremely well done as well... I hope that link is still working.

I can't get the one for Justice to work in iTunes (6 - whatever you do do not (yet) update to 7..very unstable. 7.01 is supposed to be a bit better but not perfect either)

Lost also has a great podcast as well, with a lot of cast/crew comments, but also with some spoilers(!). This is the podcast link.

Comedy Central has a fun video podcast with stand-up
( will play as mp3 if your ipod can't play video, at least on my iPod 30GB 5th it appeard in both the video and audio section ).
