I'm sure this can be done, but I don't know how. I have two TVs hooked up to my HR20, my main HDTV and a second 13" set on an ajoining porch which is fed via an old VCR (HR20 > VCR > TV set). I also happen to have an extra remote for my upstairs H20. What I want to do is use the extra H20 remote to operate the small 13" TV AND the HR20, while leaving my original HR20 remote to operate the box and my HDTV. I've already coded the extra remote to work the 13" TV, but I can't figure out how to set it up to work the DVR also. Is there a code sequence for the HR20 itself somewhere? Thanks in advance.
