The i.LINK® (IEEE 1394) connection from the camcorder is not
recognized by the computer.
Follow the steps below to troubleshoot this issue.
IMPORTANT: Some digital camcorders must be setup to output a
signal through the i.LINK® port prior to being connected to a
computer. Consult the instruction manual of your camcorder for
specific information before continuing with the steps in this
solution. Instruction manuals are available in the
Manuals/Specs/Warranty section of the Sony® eSupport Web site.

camcorder and computer.
2. Ensure the camcorder is turned on and being powered by
the supplied AC power adapter.
3. Ensure the video capture card and software are configured
properly to receive the i.LINK signal from the camcorder.
NOTES:
* Depending on the video capture card and software
you are using, you may need to manually configure the capture
card and software to receive a signal from the i.LINK port. If
applicable, check the Help files of the software or contact the
video capture card or software manufacturer for further
information.
* Sony® digital camcorders are not provided with and
do not require special device drivers for i.LINK connectivity.
The device drivers that allow i.LINK connectivity should be
provided with the video capture software. If the software you
are using does not appear to have the required drivers, you
will need to contact the software manufacturer.
4. If the issue is still not resolved, try closing and
reopening the video capture software.
5. If the issue is still not resolved, try using a different
i.LINK cable or connecting to another i.LINK port or different
computer, if available.
The troubleshooting steps listed above should resolve your
issue. If you have completed all of the steps and the issue is
not resolved, service may be required. The Sony® eService Web
site at http://eservice.sony.com/ can assist you in obtaining
service from a Sony Service Center or locating a Sony
