If you can't find any information here or any response to your question, I recommend that you phone contact your regional D-Link support office and ask for further help and information.
I found this link: http://USER_ID:PASSWORD@CAMERA_IP/dgaudio.cgi that you put into VLC for the audio. In bold are the things you change. With this you will have to press the repeat button, because the audio only lasts 1 minute and 5 seconds. This is only audio, so the video stream will have to be played on different VLC windows.
I'm running into the same time limit. Do you know if it can be changed to allow more than 1 minute?
thanks
