Pardon moi if I don't understand what all you are attempting here...I don't know jack about Prog Anything but would strongly recommend you attempt to get your setup tracking the arc with an STB before you try to go with your PC-based receiver/software. If you have already done that...never mind.
Just too much of a learning curve there with the computer-based hardware and apps, too many variables to fight IMO.
