IEEE 1394 Devices
Symptom Remarks
1. Excessive digital artifacts when viewing an IEEE
1394 device.

• TheremaybeaslowdeviceinthemiddleoftheIEEE1394network.Movethe
slow devices to the end so that connections for faster devices do not pass
through them.
2. D-VHS recordings for digital cable have
drop-outs (loss of picture or sound), or no
playback.
Digital cable signals on IEEE 1394 can exceed the data rate standards
supported by DVCR.
3. There is no audio and video from the IEEE 1394
device.

5. The IEEE 1394 device cannot be selected (is
grayed out).
The device may be busy, either recording or a peer-to-peer connection
has been established. Cancel the recording or peer-to-peer connection.

does not appear in the Device Selection menu
(not discovered).
