Here are some genealogy podcasts to consider:

http://genealogyguys.com/
http://www.dearmyrtle.com/listen.htm
http://underthetree.libsyn.com/ (A podcast for African American genealogists and historians)

Go to http://audio.genealogytoday.com/ for a listing of GENEALOGY PODCASTS & AUDIO- There are a growing number of genealogy radio shows that offer an Internet-based method for listening to them.

I'm sure a Google search will turn up more genealogy podcasts.
