As I understand it, the remotes that come with receivers, DVRs, etc often do not have all the functionality available (discrete on/off, or code to specify sound mode or input etc. - so you can't learn them from the remote as they don't exist on the remote.) I am fortunate to have used the MX-700 for years and have those that I need for all my equipment except the new TiVo Roamio basic DVR. In addition, I understand if I purchase the R40, there will be an available array of codes that will get downloaded if I choose (I can learn the remote if I want). I do not know if I will get the discrete codes until I try. So I don't know what I am missing from the Roamio box. I am guessing I will want to try to find the on/off, auto direct to MLB.com, Netflix, and You Tube (if they even exist).

I am just trying to solve the possible problems before I buy.

Is there an MX-700 or newer model out there with a software MX editor like program for the consumer?

Thank you for your reply, I have learned a lot.
