"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!"
It's not the broadcast flag cause it's only happening to those watching NBC via cable, not OTA.
Not true, I got this same message a few days ago while trying to record OTA in HD. I remember spending about 20 min trying to find a way around it with no success unfortunately.
