How to Record Jadoo/Shava IPTV Box - Audio/video stream recording forums

Hi
Its been 3 Months since i am using these box, Now i am trying to know how exactly do this box works. i means do they use any sort of script and run it or what they are doing ,i am not able to understand, so i tried wireshark to track how they really work, so i got lots of logs. But i got some of the url which are following

Code:

can anyone explain me how do they really work,they use dedicated server to stream the content or they upload a video to server and then stream it?

How can i record the video also from these IPTV Box,I Shall be very thankful to you if you guys could give me any sort of lead in this matter.

Thanks
