If your satellite receiver has an NTSC RF modulated output (RG 59 F connector), you'll need a TV tuner card in your PC to watch it.

If your satellite receiver outputs NTSC composite (unmodulated, RCA cables: yellow, red, white), you can use something like ADSTech DVD Express to connect to your PC using a USB port.

Once you've got your receiver interfaced to your PC or other display, you'll probably need to download the latest programming guides / channel assignments into the reciever using USB or serial cable.

Due to various countries legal restrictions, finding such bin or autoroll files, even for Free to Air satellite programming, is most easily done by word of mouth.
