Query: Too Much Buzz in Mic

I should have known when the install disk would not execute on either the Vista or XP machines that this moght be a dud. The microphone on one of the cameras died after 3 uses. Unfortunately, an internet search on how to get rid of the screaching noise revealed that this is a common problem.The software interface for the camera makes it clear that this is not really a Microsoft product. They must have re-branded someone elses software (and maybe hardware).Don't buy this thinking you are getting a quality product from a major company. It's junk.
