Connection to the Sony Media Changer/Recorder is lost in Windows XP Media Center Edition 2005 (911990)

CAUSE

These problems may occur if either of the following events occurs when Media Center is running:

An IEEE 1394 device is connected to the computer or is disconnected from the computer.
You put the computer on standby or in hibernation, and then resume the computer.

The IEEE 1394 bus is reset when either of these events occurs. The problem occurs because when the IEEE 1394 bus is reset, the connection (Login\Reconnect) to the changer fails. Therefore, Media Center loses contact with the Media Changer/Recorder.
