I have the 880 and HR20-700 also. The remote that came with the DVR has the 30 second skip button. I tried to learn the code to the forward skip button on the 880 and it does nothing. During the learning process it confirmed it learned the code.

I tried this several times with no success. Ideas? I have learned other keys from other remotes, not a problem there. And, I tried raw mode, still no can do.

Thanks in advance!
