EZEd:...If this does allow full control of the STB from the PC then I hope it puts pressure on the cable companies to drop their Draconian methods of not allowing the digital signal out through USB and Firewire. I don't know why they ever went the cablecard route to begin with. The cableco STB (Dish/Direc box) could work just fine as an external periferral to a PC without any other kind of interface except for a software driver and a USB connection. If they wanted to maintain encryption they could still do that from the head end and implement the copy rules...
CableCARD wasn't the idea of the cable co.s. If it were up to them, they would only let you rent a box. They were required to let other devices onto the network, so CableCARD was born. See http://en.wikipedia.org/wiki/CableCARD for more.
Wikipedia:
While you may be ok with a STB hooked to your computer, most people actually want fewer boxes. They don't want to hook it up through USB or Firewire, they want it all built into one box (perferrably the TV for most people). This is what you will need for Media Center to become main stream, and CableCARD brings us closer to this. I'm all for more laxed DRM on it, but lets be realistic, going with another box really isn't the answer most people want.
As for the Firewire comment, the box already puts out a video signal over Firewire, and if you have the right TV you can use this. Tim Moore's FireSTB also tried to take advantage of this, though it wasn't 100% successful.
Just my $0.02.
