Cable company reps tend to get real friendly once you mention that they're required by the FCC to provide cablecards that let you access their channels. The rep who was initially trying to schedule my install was trying to tell me he didn't see why the Tivo should need 2 cablecards, but got much more cooperative once I mentioned the above. Mention the FCC thing then request that the technician be on a three-way call with Tivo at the time of the install. Good luck. I hope you don't have to return the Tivo.
