Dead Tivo

Came home from my business trip - my sedan driver even rushed back to make sure I was back by the time Big Brother 10 started.
My Tivo Series 3 HD was cheerily recording something, I grab a beer, plop down into my comfy orange chaise and switch over to OTA (Over the Air) for BB10 on CBS.I’m greeted by stuttering video and audio dropouts. Shitzen!!
By this time BB10 has started and I’m fuming! Pull the plug on the Tivo and it slowly reboots back up 15 minutes into BB10.
I give up and have a drink.
Now its’ rebooting on it’s own. I’ve repeated the guided setup to no avail - it’s still locking up and having audio and video issues.
I think it’s time to take out a .22 and put a bullet in it’s little Tivo head.
