Ever since a recent update on the STB, the box will act as if I pressed "0" whenever I use the TV's remote. Doesn't matter what button I press on the remote (volume up/down, input select, arrows, etc), the box reacts with another "0". Also happens when I use the fios remote for volume control, since the fios volume uses the tv's remote code.
This is brand new behavior. I have had this setup for at least a year now, and it only started with the new update to my stb.
