Obviously depends on your interests.

I do a video & podcast every week that covers startup lessons, venture capital advice and deals funded for the week. It's called This Week in Venture Capital. http://thisweekin.com/thisweekin-venture-capital/ (there are links to there to the free iTunes download.

Also, This Week in Startups is great because it profiles startup CEOs and talks about the week's news. Hosted by Jason Calacanis and is here: http://thisweekin.com/thisweekin-startups/

Other recommendations: www.mixergy.com - Andrew Warner is great and profiles successful founders.

And I live TED talks.
