Comment(by eric at lisaneric.org):

 I've seen this or a similar problem also with a Motorola DHC 3200.

 What seems to be happening is that my cable box is actually jumping back
 and forth between node 0 and node 1.  I set up a cron job to run
 plugreport hourly and dump the result to a log file.  The box has GUID
 0x001aadfffe47916e, which usually shows up as node 0, but sometimes as
 node 1.  Here's an excerpt:

 The box appears as node 0 at 18:41 and 20:41, but at 19:41 it was on node
 1.  (That was the only time I captured it on node one since I set up the
 script.)

 It seems like whenever a node flip happens, the mythtv backend loses all
 ability to control the box until the backend process is restarted and then
 everything works fine after that for a few hours to a few days.
