I own three USB Hauppauge 950Q TV tuners. I have not used any of them to watch TV in a few years. I use them to record outdoor cameras for security.
So I launched one that was not in use, with both Windows Media Center (WMC) and also the Hauppauge WinTv v7 program. I prefer WMC. I programmed them years ago but I believe I used Analog or Analog Cable settings (can't go back without erasing old settings). I removed all the french channels from the list during setup but I still "today" get all the unscrambled basic channels, not remembering the french ones, I am left with Channels: 3, 6, 11, 13, 18, 21, 22, 27, 36, 37, 39, 40 and 48. WMC is so cool it even detected that a channel had switched position since I programmed it and corrected old channel 43 and placed it in it's proper place on position 40 (one of the PBS channels) . I also prefer WMC because it is more stable when changing channels, it provides FULL 2 week TV Listings and displays channels call letters, and a whole lot more.
Again, long time ago, but I remember that during the setup under Windows Media Center I was asked for my postal code and it then found Videotron as a provider and asked if I wanted Digital or Analog?. You need analog.
You may need to visit Hauppauge's site to check if you installed the system in the right order. They have a type of Clear program to reset everything if you want to start over and make sure.
I wonder if this will help you other than to let you know it works somewhere. I also seem to remember that the "IN" cable to the USB HVR 950Q must come from a splitter that is installed before the Illico box and NOT as a passthrough from the Cable OUT of the set top box itself. I'm a little bit fuzzy on that one. Mine are from splitters. Again, I didn't even remember that cables were plugged into my 950Q cards, I had to check.
Best of luck. Hope this helps.
