Which of my replies implied you don't know anything? If one Did, I apologize.
I was asked if I replaced batteries and if I rebooted. I replied I had done both. You asked what type of reset I did, I said I did a soft boot, you asked for a definition of a softboot. You took this off topic with your reply of "Reboot via the Menu's is a Proper reset". I am guilty of keeping that off topic portion going as well.
For the record, I have replaced batteries. I have performed a "proper reset". I have performed an RBR. I have performed a power cycle by removing power from the DVR.
I have reset the remote to factory default. (several times)
I have even tried using the remote from my HR22. Model number I think is RC64R. It has worked great with the HR22 for over a year. I get the same delay of response on the HR24.
I have tried StoneCold's method of disabling the 2-way comm between the remote and the DVR.
No luck.
