It seems from what I can tell, if you use Comcast, you are pretty much out of luck when it comes to direct IP-control for the STB.
The Tivo Premiere, which accepts a cable card AND is fully IP-controllable, seems like the only device of its kind for a cable TV STB.
Am I missing anything else?
And most importantly, is direct IP-controllability in a Tivo STB that much better than going with a standard Comcast STB and an iTach IR2IP? I understand you give up the ‘feedback’ or two-way communication aspect, but is it fundamentally a different experience in Roomie?
