cable tv box viewing software

I recently had one of my cable boxes connected to my PC and all we had to do was click on an icon for a particular software after turning on the cable reciever box, The trouble is I recently had to do a repair reinstall of my Win xp and I cannot find or reinstall that program we thought it was Intervideo but that is not panning out!

If someone can direct me to the correct software, I can once again let the grandkids watch their cartoons and other programming and I can reclaim my TV after school !!!

Thanks
