I may be confused with your question. If you do not want to use the Channels DVR just do not pay for it?
If you subscribe to Playstation Vue Video Streaming Service (I think you said $60 per month Elite) you can simply use the Playstation Vue App on a number of hardware platforms. I use Apple TV Box.
There are a lot of streaming services like Playstation Vue that work similar and most have a Cloud based DVR.
Others here simply love the Channels UI and DVR Experience. So this new TVE Feature allows us to bring our TVE Subscripts (like PS Vue) into the mix of sources.
Hope that helps.
