I currently have a hr20 and r15. these are both in my living room hooked up to different inputs on my main tv with composite and HDMI cables. I also have component cables running from the hr20 to a distribution box and 3 additional tvs that are used sparingly. I control these with rf remotes. Everything works great. Will this setup still work once I upgrade to MRV and replace the r15 with hr?. I really only want 2 boxes. thanks for any input.
