I recently switch from Spectrum to Frontier FIOS. Despite some of the usual confusion, I did get my Roamio up and running with cablecard. However, I quickly discovered I was missing a few important channels. No problem. I'm OK with paying a little more to get what I want. The CSR tells me that they only support cablecard for the basic "Custom Essentials" plan. Upgrading to the "Prime HD" package requires their DVR. I am pretty sure this isn't true. Can anyone confirm? What are my next, steps?
