Alf, as far as I'm aware there isn't a dedicated podcast on woodworking, the closest I could find was through itunes podcast directory and that was a discovery channel production which was more aimed at the DIY Market.
For those who might not understand podcasts and how they work, here's a quick explanation:
A podcast is an audio file (usually MP3). On this audio file may be recording of a DJ, music, interviews etc. Its kind of like a small radio program. What makes podcasting different to just MP3's is that with the appropriate software (iTunes is a good example) you can 'subscribe' to a podcast, very much in the same way you might add a blog to your newsreader.
The podcast is an RSS file which updates each time a new podcast is added, so everyone who has subscribed will automatically download the lastest 'cast. You don't need an iPod to listen to podcasts, any music player on your computer will play them.
Another way of thinking of it is like 'time-shifted' radio, once you download the podcast you can listen it to it as many times you like and when-ever you like. A podcast producer can now include video, images and shownotes, so when you download the latest episode of the podcast you will automaticall download the new content.
If anyone would like to try this out with existing podcasts, I highly recommend iTunes, you can download it for both the mac and pc here:
http://www.apple.com/itunes/download/
Once you have installed and opened iTunes, on your left handside in a list you should see an option 'Podcasts' this is where all your subscribed podcasts will appear. To add a podcast click on the link at the bottom of iTunes that says 'Podcast Directory' this will take you to their online directory.
From here you can search for a podcast or look at the top 100 podcasts, to subscribe to one click on the name, and then there should be a link that says 'subscribe' - click on that and iTunes will add it to your podcast link and start to download the current episode.
Podcasts are free and are usually made by amateurs, however a lot of the professional organisations are getting in on the act also, and highly listened to podcasts can also make money through advertising and such like.
If anyone would like any further information, feel fee to ask, otherwise if anyone has any idea's for content and what you would like to hear/see in a podcast please chip in!
