this problem came out of nowhere. when my dvc30 is not recording, and i shake the camera, there seems to be something inside the camera moving back and forth. when it's actually in record mode, it doesn't make that noise when i shake it. it seems as if something has come loose inside. not sure if anyone else has had this problem.

As n00be myself, I can actually answer this one =) The squirrels inside the camera have left their nuts out of the cage.

From what I had been told it's the Image stab device causing it. When there is no power to the camera, the device is slack so it clunks over to one side or the other as the camera is rolled or tilted. When the power is on, the device is caged and locked up (tight so to speak) thus not making any noise when tilted. This is totally normal and no need to be concerned.

However, feeding the squirrels inside once in a while will help.
