I was at my stepfather's house to watch the Super Bowl, he had just replaced his original S3 with a premiere, because the S3 was having issues. We were watching the Sandy Hook kids sing "America the Beautiful" and the picture was was breaking up slightly. I figured it was a problem with his cable.
Then the Tivo reboots -- "Uh-oh-- well it should be back before we miss too much of the game"
And then . . . . .
GREEN SCREEN -- "Tivo has detected a serious problem which may take 3 hours to repair"!! AAAARRRGHHH!!
Fortunately we ran to the local Home Depot, snagged a digital antenna and swapped the TV over to that. As the Premiere is still relatively new (even if it is a refurb) I told him to to contact Tivo and have then send him another one.
