| You know Sonys with that delay for the picture to appear all at once
| after it warms up. Maybe that normal delay is when the impatient
| customer is hitting the remote again and again.

| and hit the enter button, expecting a quick response, puzzled. That
| machine has it's own normal delays. Maybe so for the Sony problem...
