Thank you for the replies.
Wajo- I'm aware of the auto-clock issues and always check to make sure it's off when resetting the time.
waldwolf- I was just changing the rf cables, first hooking it up to a DTA and then switching to another to go directly to the t.v. I was working behind the unit and I don't believe it was moved. It was on, but not recording or playing back.
I did a reset a while back after I installed the firmware update, no error messages and it didn't help with the problems.
It was repaired at the Torrance facility. Guess I'll have to call them again. sigh.
