Hard disk speed
If the hard disk works too slow, the PC cannot save the digitised images fast
enough and the drop-out rate increases. The drop-out rate is the number of
images which are not saved during capturing. This results in jerky playback.
Your hard disk should offer a transfer rate of 5 Mbytes/sec under Windows.

images which are not saved during capturing. This results in jerky playback.
Your hard disk should offer a transfer rate of 5 Mbytes/sec under Windows.
To take advantage of the full transfer rate, the option "DMA" should be
checked in the Device Manager for your hard disk (see "Settings in
Windows 98SE and Windows Me" or “Settings in Windows 2000 and
Windows XP”).

HARING
Our capture board supports PCI interrupt sharing. This function is necessary
if the motherboard allocates a single interrupt to all PCI slots. In this case,
all PCI devices have to share one interrupt which means that every driver
has to check if the current interrupt comes from its device. If this is not the
case, the driver must not handle this interrupt and has to pass it to the next
PCI device. If only one of the devices involved (or its driver) fails to do so,
the system will not function properly.
