Thanks for the reply concerning debug errors and timings in the 'Image Processing' thread.

I have been reading the forum trying to find an answer to my question but no luck. Is there a difference between running the DFG/1394-1 on a laptop to a desktop PC?

I have a Sony VAIO 800Mhz 256Mg RAM with a IEEE1394 3 Port PCMCIA Card, when running my application I can import all RGB8 resolutions, I can import RGB24 320x120 and RGB24 320x240. Any resolution larger than this and the application will pause and return and Internal Error. (see attached GIF image)

I also have a Dell Desktop PC 1Ghz 256Mg RAM with PCI 1394 Firewire Card. This application imports all RGB8 resoutions and RGB24 resolutions.

What is the difference that prevents the laptop importing the higher resolutions.

My program does not support RGB32 at present so I cannot test this resolution.

Thanks David

The problem is, that some Laptops and some PCMCIA cards will slow down the FireWire port. In this case to many packages from the DFG/1394-1 to the Laptop will be lost and the driver shows the internal error message. The only solution is to test another PCMCIA FireWire card in your Laptop.

Thanks for the information. I was under the impression that a PCMCIA Firewire card would be a better option than using the Sony VAIO built in firewire port (i-Link port).
After finding myself a 6pin to 4pin cable and running my application again, I was able to import RGB24 768x576 with no problems.
Thanks once again for your help
