Have had my SB 500 for more than four years with little to no problems after the initial learning curve. I have generally used the SB at our weekend place and at home on my Windows desktop for convenience. I have accessed it with the desktop app on Firefox an MS/IE, through a Roku/android app, and through a Western Digital TV Box. In December we moved and have changed from Verizon FIOS to TWC/Spectrum with an Arris DCX-3600-M DVR. Finding no exact remote for that DVR, I have used a TWC universal remote as well as the Motorola 3400-M. The remotes are not exactly the same as the one I have, but they are darn close and they operate the DVR.
Except that in the last week or so, I am unable to remotely control the DVR at all. Whatever is on the DVR when I go to "watch" is what I get. When I hit a button on the remote, the picture hesitates briefly, but does not respond to the command. I have tried "updating/resetting" the remote remotely, to no avail. When I update the set-up using the SB and its own remote, I can then control the DVR using the various methods (desktop, android but not WD TV Box as it is at the other location) but I am the unable to do so the next day. It's back to no-control
Any ideas and/or suggestions much appreciated. The box is now basically useless to me. Thanks.
