When you are transferring Isochronous data from a device connected to an IEEE 1394 bus, the transferred data may appear to be incorrect (corrupted) or be received later than it was sent by the IEEE 1394 device. The symptoms of this problem may appears as glitches in or repeated sections of audio or video streaming data.
This problem only occurs under the following conditions:
- The Isochronous data is received by a computer with at least 4GB of physical memory, or with physical memory located at physical addresses above 4GB.
- The computer is running a version of Windows that support more than 4GB of physical memory.
This problem does not occur on computers with physical memory located at physical addresses entirely below 4GB, or running a version of Windows that does not support more than 4GB of physical memory.
