This chapter gives you important hints as well as tips & tricks on the subject
video capturing.

ARDWARE REQUIREMENTS
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.
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 Me" or "Settings in Windows 2000 and Windows XP").
Memory
In general: The more memory available, the better.
Video source requirements
If you can choose between the Composite- and the S-Video input, for
quality reasons prefer the S-Video input.
E -IDE
NHANCED
With some E-IDE hard disks, high data rates result in an unsmooth playback
when playing back video files, because the hard disk is recalibrated while a
file is read. This is not a malfunction of our product but is due to the
functionality of your hard disk and the other system components.
If you have received a disk with special busmaster drivers with your E-IDE
hard disk and/or motherboard, please install these drivers in your system,
because the disk performance will be improved considerably.
For accelerating the transmission of large amounts of data like in this case
the video data, activate the DMA (Direct Memory Access) for all hard disks
of your computer (see "Settings in Windows Me" or "Settings in
Windows 2000 and Windows XP").
