Everything on the remote (RC64) works fine except for the number keys (1-9,0). All working buttons are quick and responsive. I currently need to scroll forever through the guide to switch channels. Which is to say the least #@&#$%* annoying. I opened the remote and took it apart and cleaned the board and rubber button cover with rubbing alcohol. This improved the working keys even more but still failed to fix the number keys. Is this a bad remote, or a bad software problem? Thanks!
