We have 3 tv sets with 3 tivos. Starting a few weeks ago, they began rebooting a fair bit, usually together. Then it got to be several times a day. By last week, when I called DTV for help, they were going off 5-7 x a day. Medic came Sunday, tried dealing with each set individually--by then 8-10 times per day. (He didn't really believe us about the synchronizing.) Called him back Sun aft (don't like calling DTV on this--they dock the workers if there's any hitch), he's coming back this aft.; says only thing he can think of is to replace the multiswitch. Starting a 5:50 something this a.m., it's been going off roughly every 18-22 minutes, and taking 8-10 minutes to reset. Two of the sets have been mostly synchronized on thiese starts--4 out of 5 exact times; 5th within 5 min. of each other. 3rd set I haven't kept track of as much, but it doesn't seem to be going off as often--maybe 2x in 3 hours--& it's fits doesn't match up to the others at all. What's going on? Has anybody foound a fix?
