My older Motorola DCX3400M PVR started showing the word "HUNT" on the LCD display yesterday. It seems to be there for about 30 seconds every 5 minutes or so. Everything seems to be working ok, and there have been no changes to my system in a long time. About the only issue I see is that it seems to take a fraction of a second longer to change channels, although that could be because I'm looking for issues.
What does HUNT mean in this context, and if necessary what can I do to rectify the issue?
