Marco Baringer's SLIME tutorial screencast is quite good. Other than that, I haven't seen much else that's worth watching.

We have 50+ developers that are using Emacs, and a dozen more that have never used Emacs but need to do so in the future. I regularly drop coin on training materials for our design staff, but there are no compelling AV materials for our developers. There is no company equivalent to Total Training for most developer and sysadmin tasks, for example, unless you want to get an MCSE or something.
I've spent over $75K on video training for our designers this year (Total Training, Lynda, NAPP, etc.), but our developers usually end up using online documentation and a few books. I think there is a market opportunity for developer-focused video/multimedia training materials. And sysadmin stuff too, for that matter.
