First, Aharon won't see this any time soon. His first kid was due last Friday and, as far as I know, is still on deck. Not that things will get easier when Junior actually arrives. :-)
Second, the primary tools that Aharon uses are Camtasia for capture, and Squeeze for compression.
He goes into great detail on this and MANY other web video-related topics in his Cow Master Series DVD,
"Internet Killed the Video Star."
Among my very favorite parts of it is indeed the section on creating podcasts -- not just the compression, but also posting and publishing via iTunes and other podcast subscription services. Also great stuff on other kinds of podcasts, including straight-up video podcasts using Adobe Visual Communicator (one of the most remarkable pieces of software I've ever seen).
In typical Aharon fashion, it's topflight info presented in truly entertaining fashion. There's not another disk anything like this. Follow the link above to check out the first chapter, absolutely free, and you'll quickly see why this is the best-selling disk in Cow Master Series history.
All that said, the answer to the only question you actually asked is Camtasia and Squeeze. :-) But your stuff won't look like his until you know how.
