The information in this article applies to:

- Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use the Hauppauge Win/TV video system with Windows, you may notice the
following limitations:

- The color magenta (purple with red) does not display correctly. This is a
  limitation of the Hauppauge video, and may apply to other television video
  boards also.

- You may experience problems loading and saving still-frame pictures.

- You may experience difficulty using WinTV with Microsoft Video for Windows.

In addition, the 16,000,000 color mode that some video adapters support will not
work with WinTV.

MORE INFORMATION
================

Win/TV is a combination hardware/software system that allows Windows users to
view full-motion video and television in a resizable window. Win/TV also allows
Windows users to capture screens and save them in a variety of graphic file
formats (for example, BMP, GIF, PCX, MMP).

In order to use Microsoft Video for Windows, the WinTV card and software must be
revision 'D' or later. To upgrade the card, you must return it to the factory so
that the IRQ can be reset to IRQ 15.

Magenta Displays Incorrectly
----------------------------

The magenta display problem occurs because the Win/TV system uses a technique
called "color keying" to mix the computer's standard video signal with a
television signal generated by the Win/TV hardware.

The color keying process does not actually send the television signal through
Windows. Rather, the Win/TV software fills its on-screen window (the display
area) with a solid block of magenta and sends the location of the display area
to the Win/TV hardware.

When the video signal is sent out from the computer's video adapter, the Win/TV
hardware superimposes its television signal over any occurrence of magenta that
lies within the bounds of the display area. Under normal circumstances, this
allows other windows to be displayed on top of the Win/TV window.

Problems Loading/Saving Still-Frame Pictures
--------------------------------------------

If a computer has 16 megabytes (MB) of RAM installed, the user should upgrade to
WinTV version 2.03 or later. This solves the problem of loading and saving
still-frame pictures. The current versions of WinTV can save and load
still-frame pictures while Windows is in 386 enhanced mode only. This is by
design.

Using WinTV with Microsoft Video for Windows
--------------------------------------------

To use Microsoft Video for Windows, the WinTV card and software must be revision
'D' or later. To upgrade the card, you must return it to the factory so that the
IRQ can be reset to IRQ 15.
