Hello new to the dvr thing and hoping someone here can help me I recently purchased an everfocus edr810h I only hooked one camera to it to test it. The problem im having is the audio is fine but the playback video is choppy and not in sync with the audio seems about one second behind . What i mean by choppy is for example if a person walks by the camera it looks like they are I guess stuttering not sure how to explain it better than that. Hope someone can help. Thanks Kevin
