[SOLVED] Using libVLCsharp to stream pw protected IP Camera Video but video not playing

I am trying to construct a UI for Onvif complaint devices. I've been beating my head against the wall for sometime now. I believe I have the custom URI correctly constructed. According to the ONVIF Programmers Guide we need to Get Profiles, GetStreamURI, Request Streaming. http://www.openipcam.com/files/ONVIF/ONVIF_WG-APG-Application_Programmer's_Guide.pdf

Using Wireshark I believe I see HTTP packets being sent (showing the appropriate requests), and what I believe are appropriate responses. The final GetStreamURI gets a successful response from the camera. Then when I try to call _mp.Play I see a few packets over HTTP and a few TCP packets back back from the camera. After this communication stops.

            }
        }
    }
}

Update: I believe my issue is the URI I have built requires validation. When I take this URI and put it into a web browser I get a 401 Error. I'm not sure why I don't see this error on wire-shark. I assign the user name and password into URI object but when I check "IsWellFormedURIString" I get an "invalid Port Error."
