Firewire Channel Change GUI (for STB Motorola 6412)

I am new to the forum and hope this isn't in the wrong section. I currently have my STB Motorola 6412 hooked up to my pc via firewire. I am running Vista and have had no problems watching or recording channels. I also installed Timmoores firestb channel change program which appears to be command line only.

I thought it would be pretty simple to find a gui or program that would allow me to change channel through the firewire via a gui or more a less a pretty remote sitting on my desktop. To date no luck.

Does anyone know if this is possible and whether such software exists. Any insight would be appreciated.

One more thing, I don't have an analog tuner card, just the firewire connection. Thanks
