"I've found myself using my PC for a lot of conversations lately, and I'm also considering recording a podcast to share with anyone who will listen. There are tons of USB headset / microphones out there, and I'm hoping someone has some solid recommendations based on experience. I'll consider both headsets and standalone mics, by the way, but I'd like to keep the bill under $100 if possible. Help!"

The word on the street is that the authoring software for Blu-ray didn't support VC-1 in time and that future titles will be VC-1, but who knows if that is true. Only time will tell.
