The “waiting for incoming stream” status appears when the encoder disconnects from a VVCR stream before you stop the DVR recording.
For example, if accidentally ended your stream on your encoder or if the encoder loses power or internet.
DVR automatically ends the recording when it loses the signal from the stream. It then creates a new recording with the “waiting for incoming stream” status. You shouldn't lose anything from before the stream disconnected.
The second recording will automatically start when you reconnect your stream.
