Here's a doozy.
I am an RCN customer. I wanted to get TIVO stream so I read here, from an RCN engineer who had posted, that if I got a Quad 4 TIVO and a Preview to replace my 2 Premieres, that the TIVO stream would work. I had RCN come out and set up the Quad 4 TIVO and the Preview and set up the MOCA networking which was required for the TIVO stream to work and for the Quad 4 to work with the Preview. Everything was fine. I then ordered the TIVO stream through TIVO. It arrived. I had the TIVO app on both my Iphone and Ipad (most current versions of the software). I plugged in the TIVO stream for both power and ethernet connection through the router. I put in the Media Access Key to the Quad 4 on the IOS apps. The Apps recognized the TIVO stream but said that I needed to activate the stream. I went on the TIVO site and put the service number of the stream into the activation bar. I was then notified that the stream was preactivated by TIVO. However, the App would not recognize that the stream had been activated.
I called TIVO customer service and told them about the problem and they said that RCN had to turn back on the service numbers of the Premieres in their system in order for the stream to work properly. Although this did not make a bit of sense to me (because the stream will not work with Premieres), I called RCN with this advice and they, of course, told me that the Premiere boxes are recycled to other customers and they cannot turn back on the service numbers of surrendered boxes in my account because they will be activating those service numbers as soon as the boxes are redistributed to other customers. So now, there does not seem to be a solution. None of this, of course, was told to me before I purchased the stream.
