Just looked at the Roamio for the first time yesterday, at Best Buy, discovered that Xfinity on Demand support via these TiVo DVRs is now available in my market.
My understanding is that the same "2-way" communication that enables this is what makes Comcast cable boxes capable of posting Caller ID information to the TV screen when calls come in.
Any idea whether the Caller ID on the TV happens with an "Xfinity on Demand" capable Roamio?
I read a few ancient threads in the help forums that talked about placing an external caller ID box between the phone jack and the TV as a way of implementing this, but they also mentioned that doing so blacks out the TV screen while the phone info is being displayed, and that the phone info shows up on any recordings made using that approach.
I didn't bother to ask the "Geek" at Best Buy once he told me that
1. He'd never heard of expander drives
2. Even if they existed, he was certain that they didn't work with Roamios
3. He appeared incredulous when a customer who overheard my question pointed out that the Roamio DOES have an eSATA port for exactly this purpose, AND that the basic drive in the Roamio can easily be swapped for a larger one in order to avoid the foibles of expander drives anyway (the Geek was clueless on each of those points).
