Have you try just installing the driver not the software itself?
What device are you using with windvr3?

Frontech USB TV Box

With the windvr3 open right click and check that your device is checked in the settings.

How do i select tv box. it is showing as Frontech USB TV Box on Top.
Give you mail id i will send a sceen shot.

Is the source to the left of the device set to tv not composite or s-video?
