I just upgraded my DVR to a Fios One vms4100 box. The previous set top box was able to be completely controlled with my Logitech Harmony 650 remote. Since upgrading the box, I am unable to use the "rewind" function. The Fios remote works properly but the Harmony remote will not operate the rewind function even though the light on the Fios box flashes indicating its receiving the command.
Although all the other functions on the remote appear to work (I haven't used all the functions on the new box yet though) without reprogramming the Harmony, I did connect the remote to my computer and removed the old DVR box model and entered the new Fios One box model in order to rule out remote code software. The remote is up to date with the latest Fios one box model and remote codes now and the box is receiving the commands, but it's not working this rewind function (and possibly others).
I've seen this question raised previously but it was never answered. Thanks.
