Aviation Podcasts

I am totally amazed at how many aviation related Podcasts are available for
free on the internet.
Not to mention that there are some really great Video Podcasts out there.
Am I the last one to find this out?
Has anyone else in this group ventured into the world of Podcasts?
It is overwhelming, a brief internet search turned up enough IPod videos for
me to
stay busy for the next month. And I'm only talking about the ones that are
free,
there is also videos you can purchase.
For example "Sportys" now has many of their videos online for download to
an IPod for half the price of a DVD.
