Does this box have an IEEE-1394 (FireWire) port? If so, you might be able to 
use that for channel changes, even if your cable company encrypts everything 
coming off that port. I've got a Motorola box from which I can extract video 
via FireWire for most channels, but even for the channels that come over that 
port encrypted, I can still use the FireWire port to tune the channel, which 
I then capture via S-Video output to a Hauppauge tuner card.
