Hi

I'm trying to use my DMK41AF02 on my new MacBook Pro (running Windows XP).

I've installed the latest drivers, and the camera is recognised, but it says "Error: :Live Mode could not be started. Please make sure no other program uses this device and that there is enough bandwidth on your firewire bus available".

My MacBook Pro has the 9-pin 800mb firewire connection, so I bought a 5 metre 9-pin to 6-pin cable, and expected that the DMK41AF02 could get power through that.

Is that correct?

What might the problem be?

Cheers

btw it's a 5m cable if it makes a difference.

I've also tried 2 different powered firewire Hubs.

9-pin in the Macbook Pro to 6 pin in the powered hub, then 6-pin to 6-pin from the Hub to the DMK41AF04.

In both cases, the device is recognised and I choose it from the list, but I get the same error message each time.

So whether I use a powered Hub or not, I get the error message.

Please help!

Hi,

I would like you to try lower frame rates. Also, Windows XP SP2 has a problem with 1394b interfaces. The Performance of 1394 devices may decrease after you install Windows XP Service Pack 2

Please refer to http://support.microsoft.com/kb/885222

After you update your computer to Microsoft Windows XP Service Pack 2 (SP2), the performance of your 1394a or 1394b FireWire devices may be greatly decreased. A digital camera that uses S400 speed is an example of such a device. This problem occurs if you connect a 1394a or 1394b FireWire device to a 1394b port. This problem occurs because Windows XP SP2 changes 1394b ports to S100 speed when you upgrade.

It seems the issue was not fixed in SP3.
