said by PseudoShootr:I had issues with my box for the first week until I did a factory reset on it. Once I did that, all was good. I do get the error code you mention occasionally but I've found that it occurs (IMO) when the box times out after a period of no viewing.
A push of the guide button brings it back to life and it's good to go.
Most times a channel change or opening the guide works for us too, but ~twice a week absolutely nothing works. Not even a power cycle. We just have to sit and wait for it to eventually start working again (usually about an hour).
