The most recent issue I have had with the T-Box is a new one. It became absolutely unresponsive to the remote, and the light on the front didn't flash when I pressed a button. However the T-Box continued to play video (albeit stuck on one channel) and continued to record its scheduled programs. I left it overnight because I was recording something and didn't want to reboot right then, and it was still stuck like that the next day.
As an interesting observation on the subject of the T-Box remote, we have this issue fairly regularly (non response to the remote) and put it down to the remote rather than the Box, our "fix" is similar to banging an old B/W TV we take off the battery cover and reseat the batteries and roll them in their housing a few times. It seems to work.
