When you connect two digital video camcorders to two different Institute of Electrical and Electronics Engineering (IEEE) 1394 adapters and you are running in the Camera mode, the first camcorder you attach to the computer may works correctly, but the second camcorder may not work correctly. Although you may be able to switch between the two camcorders in Microsoft Movie Maker, you may only be able to obtain a picture from the first camcorder.
To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows XP Service Pack 1.
There is a limitation of One digital video camcorder for each IEEE 1394 adapter. There is a limited amount of available bandwidth for ISOCH data on the IEEE 1394 bus, so two camcorders on a single IEEE 1394 controller cannot be supported. Note that this is a design limitation, and is not supported. Although some combinations of different camcorders may work in this specific scenario, Microsoft cannot guarantee this successful use of this configuration, and this configuration is not supported.
