With my new Zune, I've started watching some video netcasts.  Here are the ones I've found the most interesting so far:

• Tekzilla - Feels a lot like old TechTV.  1/2 hour an episode talking about everything from routers to Black Friday sales.
• The GigaOm Show - Om Malik interviews headliners and comments on the Web 2.0 world.
• DL.tv - Another technology news show.
• Cranky Geeks - John Dvorak hosts a panel discussion about the latest trends in technology.  Think Twit but with video.  Not quite as good though.
• Ask A Ninja - Short form comedy.  Hard to describe.  Just watch it.
• Tiki Bar - Comedy show set around the adventures in a tiki bar.  Well written and high production value.

If I'm missing any good video casts, let me know.
