IP Camera 401 unauthorized Error - c#-4.0

Question

While connecting IP camera with C# app, i found the simple player in Aforge/Samples/Player. It just needed modifying the ip string so i added mine admin:admin#192.168.1.239:81/videostream.cgi?rate=11 to get MJPEG video stream. On compiling i get error as
The Remote server returned an Error (401) Unauthorized.
Andre Kirillow mentioned in MJPEGstream.cs file
Some cameras produce HTTP header, which does not conform strictly to standard, what leads to .NET exception. To avoid this exception the useUnsafeHeaderParsing configuration option of httpWebRequest should be set, what may be done using application configuration file.
<configuration>
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
</configuration>
well there are two ways to do this as suggested by Dinis Cruz. I added the .config file wth the above code and also did it programmaticaly but same error persists. The Player program coding is

From google i added some open ip cameras and there video stream was captured and worked fine but my camera returns Error 401. Then I used ISPY software recently made by Sean Tearney that was built using the same Aforge library and it captures my camera's video stream:p. Now i do not know what's wrong with the simple player's coding.Kindly if some one can help me get the video stream from camera. Thankyou

Answer 1

most likely because the camera is protected by password. to enable you to view the stream, please provide username and password to the camera you try to access.
for jpeg stream:
jpegSource.Login = "your username";
jpegSource.Password = "your password";
for mjpeg stream:
mjpegSource.Login = "your username";
mjpegSource.Password = "your password";
