Difficulty installing v5 on Raspberry Pi

[davidbb]

I have managed to download , unzip and run the commands as shown in the sticky note, however i cannot seem to run the software or even find how to ?

This is the commands and replies i get to the chmod commands and ./NextPVRServer

Can someone help ? I am totally new to the Raspberry Pi and have just done the initial install of Raspbian.
Here's the message i get when i run the commands ?
Once installed properly, where do i access NextPVR on the Pi ?

pi@raspberrypi:~/NPVR $ cd NPVR
pi@raspberrypi:~/NPVR/NPVR $ chmod +x ./NextPVRServer
pi@raspberrypi:~/NPVR/NPVR $ cdmod +x ./DeviceHostLinux
bash: cdmod: command not found
pi@raspberrypi:~/NPVR/NPVR $ chmod +x ./DeviceHostLinux
pi@raspberrypi:~/NPVR/NPVR $ ./NextPVRServer
