I have two "boxes". One is the DVR, the other is a "regular" box with guide and On Demand. I then have a couple other TV's in the kid's rooms with Comcast's most basic "box" (no guide, limited channels etc.). I probably could kill one of them, and if I bought my modem I'd eventually save maybe $13/month (albeit after 6 months of paying off the modem/time to modify services)
