I must be special... I posted last week that I upgraded my 3-year old 2160a (which had never had any problems with freezes or timekeeping), and the next day it froze while searching for a time signal (I pulled the plug after about 20 minutes). After that, on advice (or hunches) from some other posters, I changed my time-setting channel from an analog to a digital.
All seemed well for a few days. I recorded and replayed a couple of programs. I got my new 515 remote today (yay! little changes make it much better for me.) and went to watch a recording I made last night. After a bit, I noticed that the timer display was stopped at about 3 minutes in (even though the recording was still playing), and none of the remote buttons worked. First suspect was the new remote of course, but none of the buttons on the front panel worked either, and swapping batteries around convinced me that the remote wasn't the issue.
I didn't have the patience to wait till the recording ended to see what happened. I pulled the plug briefly, and when I replugged it, I saw military time (I remember other posters mentioning that, but I'd never seen it before) - but still no response to any buttons.
Okay, unplugged it for 5-10 minutes, but when I replugged it, I didn't hold down the power button. After that, it searched for and found a time, and the only thing missing were my timer settings.
I set up my timers yet again, and based on vague memories of various postings here, this time I set the auto-clock to OFF. We'll see if that makes any difference...
Am I the only one who's having NEW problems after applying the new firmware to an older machine? And has anyone experienced a freeze while a recording is playing? I don't remember ever hearing about that, but maybe I wasn't paying attention because MY unit didn't have the problem

Anyone have any other suggestions? I keep seeing posts about successful upgrades and I wonder what's different for me.
Thanks!
