My Tivo HD (652m) has been a problem now for several months with REBOOTS.
Things that I've done are:
1. Replaced power supply capacitors
2. Replace New HDD with new 652m.bak image (Current - Older Seagate 250GB 7200RPM), (no longer use WD10EARX)
Now I believe I may have found the problem (OTA channels only). One of my channels broadcast is SD does not have any programing information
Every time I've done a Guide setup and look at the Channel Lineup later I notice that I have to put a check mark next to the channel so it will show up in the Guide Menu.
So now I've removed the check in Channel Lineup which in turn removes the channel from the Guide Menu. Now NO reboots
.....still testing this idea. Any recommendations?
