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