Allow Screen Saver : On, will allow your system to use your default
screen saver when WinTV is open or to use the live TV as a screen
saver.

Setting full screen TV mode

Click Preferences and then click on the TV Mode tab. Set Allow
Resolution Change. If you then click on the TV icon on the
WinTV2000 Toolbar, the WinTV application will switch the VGA mode to
the chosen size (using the Windows Quick Res feature), allowing the
WinTV image to be viewed full screen.
Image Save, Print and Copy to Clipboard
The process to save, print or copy an image starts with the digitizing of
a single video frame. When one of these functions are clicked on, the
WinTV moves the next video frame into your PC's main system memory
instead of the VGA display. Your PC's processor then converts the digi-
tized video image into a 24-bit DIB image (a format which is used
internally in Windows), and then copied back into the VGA memory so
that you can see the image which will be printed or saved. This
becomes a "Thumbnail" image in the WinTV tray window. The video
images which are digitized can be saved to disk, printed to a color or
black/white printer or copied to the clipboard. These functions can be
viewed from the PREF menu:
There are a few things which need to be noted. First, because a video
frame is composed of two "fields", an odd field with the odd lines in the
image and an even field composed of the even lines, there might be a
distortion in the frozen image if there was rapid motion while the image
was being moved into main system memory. This distortion is called
"interlaced artifact".
Another item to note is that the video image, when converted into a 24-
bit DIB image, will look lighter then it did when it was in motion. You can
adjust the images brightness, contrast and color saturation and hue by
clicking on CLR Button. These adjustments are made during the digitiz-
ing process on the WinTV board and will affect both the "live" image
and the frozen image.
