I think I'd be troubled if Mike were to go for the clients instead of DVRs. I just don't get the whole non-DVR client thing.
As someone with a dozen or more DVRs, I can see how/why you don't.
With the addition of MRV, we moved from stand alone boxes and towards an integrated system.
In my case, I needed two DVRs [in the main room] and I could use a receiver in my bedroom. With this I could watch recordings, and setup recordings in the bedroom. In the main room I needed to change DVRs to setup recordings and check to-do lists, as I needed to balance them between the two for conflicts.
With the move to Genie and a client [for the bedroom], I have full access and features/functions from everywhere, without needing to change any inputs, or receivers.
