DV Cam Not Recognised

Hi Friends
My G5 DP 2.3 has decided to no longer recognise my Canon ZR 25 mini DV cam.
I have used this DV cam to import footage into this computer many times before, but tonight, nothing seems to be resolving this issue.

I have tried:
- Different firewire ports in the G5
- Different 6 to 4 pin FW cable
- rebooting the camera and the computer (many times)
- The camera is recognised by my G4 TiPB no problem.
- G5 System Profiler shows nothing under "FireWire Bus", although camera is plugged in to it.

G5 DP 2.3
3 gigs RAM

This is what it says under Network > Locations:
Built-in FireWire:
Type: FireWire

BSD Device Name: fw0
Hardware (MAC) Address: ***************
Configuration Method: DHCP
Configuration Method: Automatic
Configuration Method: Node
Proxy Configuration Method: 2
ExcludeSimpleHostnames: 0
FTP Passive Mode: 1
Auto Discovery Enabled: 0

Any ideas?

Uh Oh!

I think this is serious.
To test my Firewire connection in the G5, I turned on my external FW drives that have always worked before with this G5.

As well as the DV Cam, the external FW drives are not showing up.

What could be causing this?

I just ran the disc repair utility on the OS X install disc, and the internal drives all showed no repair necessary.

How do I run a firewire diagnostic?
Is this a matter that requires a trip to a repair shop?

Macintosh: FireWire Issue With Some Canon Mini-DV Cameras
This document describes a FireWire issue that can occur when connecting Canon ZR-40, ZR-45, and ZR-50 Mini DV camcorders. For more information about this issue, please contact Canon, Inc.


When other FireWire devices are connected at the same time as the Canon camera, one or more of the following symptoms can occur:
Devices unexpectedly disappear from the FireWire bus. For example, FireWire hard drives disappear from the desktop.
An alert box appears with this message: "The storage device that you just removed was not properly put away before being removed from this computer."
Video editing software such as Final Cut Pro and iMovie report dropped frames during capture.
The computer stops responding.
Products affected
Mac OS 9
Mac OS X
Canon ZR-40
Canon ZR-45
Canon ZR-50

Try one of the following workarounds:
Disconnect FireWire devices other than the camera. This step should always alleviate the issue.
Try a different length or brand of FireWire cable.
Rearrange the order of devices in the chain.
Note: Information about products not manufactured by Apple is provided for information purposes only, and does not constitute Apple's recommendation or endorsement. Please contact the vendor for additional information.

Make sure your DV camera is connected to the computer's FireWire port and that it is turned on.
Many DV cameras include both a USB and FireWire (also known as iLink or IEEE 1394) connection. The USB connection on DV cameras is usually designed for downloading still images and not video. Use the FireWire connection when working with iMovie. If your camera does not have a FireWire port, it will not work with iMovie.

For more information, see "iMovie 3: How to Connect a DV Camcorder to Your Computer"

If your camera is connected via FireWire and is turned on, follow one or more of these tips to re-establish the connection to the camera.
Turn the camera off and back on again.
Disconnect the FireWire cable from your computer and reconnect it. Do the same at the camera as well. If the camera is connected through a FireWire hub, try connecting the camera directly to the computer.
Make sure a tape you know works is in the camera. Eject and reinsert the tape to make sure it's correctly in place. Try more than one tape.
Try disconnecting any other FireWire devices that may be connected to your computer. If disconnecting an iSight camera appears to resolve the issue, make sure that you have applied iSight update 1.0.2 or higher.
Quit and reopen iMovie.
Restart the computer.
Try another FireWire cable, and/or try the camera with another computer running iMovie.
Damaged tape, dirty playheads, or mixed footage formats may cause a camera to stop importing unexpectedly. Click here for more information.
If iDVD is open, quit iDVD and iMovie HD and then reopen iMovie HD.
Open Apple System Profiler (it's in the Utilities folder) and check to see if your camera appears in the FireWire section.
If after following the tips in step 2 you do not see your camera in Apple System Profiler, try resetting the FireWire connection as described in "Macintosh: FireWire Ports or Third-Party Devices No Longer Work Correctly" and check again.

Check the documentation that came with your camera, or consult with the manufacturer for information on connecting and setting up the device for use with a computer.
The documentation that came with your camera or DV device should include information on locating the FireWire port on the camera. This port is sometimes referred to as iLink or IEEE 1394.
Some cameras need to be set to "VTR", "VCR", or "DV" mode in order to communicate with a computer. Check your camera's documentation for information on how to set your camera to this mode if needed.
Some analog to FireWire converters (DV bridges) may require you to change the device settings by pressing certain buttons or switches on the device. Some DV bridges may also require the installation of a software driver or firmware update to properly control or recognize the device. Consult the documentation that came with your DV bridge, or check the manufacturer's website for more information.
Some cameras may automatically turn off to save battery power. If your camera unexpectedly disconnects during import or export, connect the camera's AC power adapter.
Make sure the date and time on your camera are set correctly. If the camera uses a backup battery to prevent the date and time from resetting, check this battery to make sure it is still good. For additional information, see "iMovie: Automatic Scene Detection Requires That Camera Clock Be Set Properly", and your camera's documentation.
Some cameras allow you to record at different speeds. Make sure the camera is set to the highest speed (SP) setting before connecting it to the computer, even if your footage was recorded at a slower speed. For some camera models, the speed setting may affect how the camera communicates with the computer. Check your camera's documentation for additional information, and try some sample recordings at different speeds to make sure the recording speed is compatible.

Make sure your software is up to date.
For best results, use Software Update preferences to update your computer's software, including QuickTime. iMovie 3 users should update to iMovie 3.0.3 and QuickTime 6.3 or later. See "iMovie Updater 3.0.3 for Mac OS X: Information and Download" and the QuickTime Download page.
For best results, use a qualified device.
iMovie works with most DV camcorders that have a FireWire connection. For information on cameras that Apple has tested and qualified for use with iMovie, see the following:

For iMovie 1 see "iMovie 1.0.x: Compatible Camcorders"
For iMovie 2 see "iMovie 2: Compatibility"
For iMovie 3 see "iMovie 3: Compatibility"
For iMovie 4 see the iMovie webpage.

Tip: Devices that are not on the qualified device list may still work. Results will vary depending on the device. Consult with the camera's manufacturer for additional compatibility information.
Make sure your camera or device is designed to send DV data when communicating with a computer.
Some video cameras record data to the camera's memory, a card inserted in the camera, or a writable CD or DVD. iMovie is designed to work with the DV format transmitted over FireWire. If your camera does not support sending DV data from a FireWire connection to the computer, or does not have a FireWire connection, iMovie will not see the camera.

Depending on the format in which the footage was captured on your camera, you may still be able to use it in iMovie. If you can copy the footage from the camera to your computer's hard disk you may be able to import it. From the File menu, choose Import and select the file copied from the camera. Check the documentation that came with your camera for more information on downloading video to the computer.

For best results, footage should be in DV format. If the footage is in another format, you may experience unexpected results such as reduced video quality, loss of audio, or audio/video synchronization issues. See the following documents for additional information:

42996 "iMovie 3: No Audio With MPEG-1 Clips"
61816 "iMovie 3: How to Import a QuickTime Movie"
60561 "iMovie 2: How to Import Non-DV QuickTime Movies"
If you are using a DV converter you may need to set the option in iMovie to "play through to camera" depending on the converter model and the version of iMovie you are using.
See "iMovie: Unable to Export Movies Using Sony DVMC-DA2" for additional information.

Some older camera models may not import or export when an external FireWire drive is connected to the computer.
See "Macintosh: FireWire Issue With Some Canon Mini-DV Cameras" for more information.

If your camera frequently disconnects during import or export, or if playback in the iMovie preview pane is jumpy or choppy, make sure your iMovie project is not stored in a FileVault directory.
See "iMovie: Using FileVault Can Affect Performance" for information about iMovie and FileVault. See "iMovie 3: Unable to Play or Import Clips on Power Mac G4 Cube" if you have a Power Mac G4 Cube.

If you are using an iSight for recording in iMovie, you must use iMovie 4 or later.
In addition to DV FireWire camera support, iMovie 4 adds compatibility with some IIDC-based FireWire video cameras including iSight. See "iSight: "No Camera Attached" Message in iMovie" for more information.

If you have installed Final Cut Pro HD on the same machine, click here for additional information.

Check Audio MIDI Setup to make sure the audio sampling rate is set to 44100.0 Hz. If the audio sampling rate is set to a higher value, a camera may not be recognized properly by iMovie. See article #300832 for more information.

Thanks for the info, folks!

Unfortunately the work-around requires a work-around, and since this machine is meant specifically for video editing, this is a big problem.

jlcinc, Yeah, I had QT 7. The instructions you provided were easy to follow and I downloaded the latest QT. But, that didn't get it to work.

Ottawaman, removing all other FW plugs while the camera is attached was the work-around solution.
Unfortunately this is video footage, and I need my external FW drives attached, because that's where this footage will be stored. The work-around to this work-around is to import the footage to the internal drives, then detach the camera, attach the external FW drives, and transfer the footage over to the external FW drives.
This is awfully cumbersome, and is a major handicap to what should be a rockin', Mac, video editing set-up, but I guess it'll have to do 'til this mess is cleared up.

As another work around, would it be possible to add another firewire card?

That's certainly possible.

But would I be mistaken in assuming that this is a software or firmware issue that should be cleared up soon?
I'd rather not buy another FW card and take up more space inside this already hot and stuffy G5. Plus, if this is a software/firmware problem, might another card suffer the same fate?

(The FW ports were working fine in this machine until recently)
