I disconnected an antenna cable and re-connected to another one then re-ran antenna scan because it missed some channels. I got audio but the top 90% of the video was cut off on the lower channels. The video was severely pixellated on the upper channels. I initially thought that maybe the box or the drive was bad. I had put in a 3TB WD AV-GP drive before I ever turned it on. So, I reverted to the old standby: pull the plug and let it reboot. That did it--everything working fine. As an aside, there is no "wdidle" (or whatever it's called) problem. BTW, I have some S3 OLEDS I am going to sell. PM if interested.
