I have a VIvitar DVR 850W. When I record a video, I see the video but no audio. So I went into the congiuration to make sure the audio is on (and see the iCON on the video screen to show in fact I do have audio enabled). I've toggled the audio option, still no help. I set everything back to the default settings, no help. This is a brand new unit out of the box. Any thoughts/suggestions would be appreciated.
