As many of you know, Cox tuning adapters have a distressing habit of periodically losing all channels, presenting the TiVo with a black screen. The TA does not notify the TiVo of this problem over its USB connection, causing a total loss of scheduled recordings in many cases. The approximately monthly period of this phenomenon strongly suggests a reauthorization problem, but I'm not sure what's actually happening. In any case, the only solution is to power-cycle the TA and wait the 20 minutes or so it takes to reauthorize itself. I was wondering if anybody had tried doing preemptive power-cycle resets to combat this problem, and whether that was successful.
