PTZ Commands Not Sent on Some Camera

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Click PTZ Controller button for Camera 1 and Camera2
2. Ispy does not send a http request for Camera 2

What is the expected output? What do you see instead?
ISpy does not send PTZ commands for 3 out of 20 cameras. This was verified 
using WireShark protocol analyzer.  On the cameras that work, I click the PTZ 
controller and get.  

232096  33.545291000    192.168.1.32    192.168.1.36    HTTP    415 GET 
/cgi-bin/camctrl/camctrl.cgi?move=right HTTP/1.1 

All cameras will move if I type the http request directly in the web browser.

On three cameras, ispy does not send the http request.  This was verified by 
clicking the PTZ button and monitoring WireShark. 

What version of the product are you using? On what operating system?
Windows7, iSpy 4.6.6.0

Please provide any additional information below.
Cameras models are PT8133 and DCS-6620. All the settings appear to be the same.

I'm having the same issues.  I'm using fiddler and I don't see the commands 
being sent as well.  When I send the commands manually through firefox or 
chrome they show up and the camera moves accordingly.  

iSpy is changing the request though. when I type in 

http://[IP]:[Port]/decoder_control.cgi?command=

in the PTZ URL something gets sent to the camera.  I figured out it was sending 
the command=0.  Which points to up.  The camera tries to move up and acts crazy 
sometimse.  It's somehow sending the http request and fiddler is not picking it 
up.
