Problem: Poor TV picture quality
A poor TV image could be caused if your VGA display adapter does not have
enough video RAM to hold the TV image. In this case, WinTV resorts to Primary
Surface mode, which lowers image quality. A memory upgrade on your VGA dis-
play adapter might fix this problem.
Another possible cause of this problem could be that your VGA display adapter
does not support Windows 95 Direct Draw. In this case, you might consider an
upgrade to a new Windows VGA accelerator which has Direct Draw and support
and is compatible with the WinTV board.
A poor video picture might also indicate a bad signal. To verify a bad signal, try
one or more of these:
Move your antenna or check your cable connection.
Move possible interference sources, such as other computers or television sets,
away from your PC.
Contact the cable company to check your signal quality.
If you still experience problems, verify the signal quality by following these steps:
1. Quit the Viewer and run the Diagnostics Program. (Both programs cannot
run at the same time.) To run the Diagnostics program: Click the Start button,
then select Run then c:\Program Files\Intercast\intrdiag.exe
2. Click OK.
