"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!"
"If they didn't require a connection to the clearing house, how else could they tell I just didn't rent the movie and copy it to my PC?"
Can they tell I bought a used copy from [Enter your rental store here](already in rental circulation)?
Can they tell I bought a used copy from you? my brother?
Can they stop me from using managed copy if I wasn't the original owner?
Is there a registration process when you use managed copy on a purchased disc? Can it be transfered with a sale/trade?
Will [Enter your rental store here] get copies that are flagged for non-managed copy use?
Get back to us on those issues.........
