Codec Performance in WinTV2000 Shutsdown system on fail

The display is now divided into two frames upper is largest but bottom is a
bit over 1/3 height. Display is not definable, repeating images and mostly
white space with only black lines around the figures. This is a Hauppauge
WinTV2000 product expansion card connected to cable and S-Video and RGB
Composit. It worked fine and I don't know why the video codec is failing the
error button press to capture a frame causes Windows XP to reboot. When in
Microsoft Messenger and I connect the webcam to see the channel popsup and
the friend sees whats on cable TV. I changed the driver for the webcam and
this problem has been resolved so it still has a codec problem in WinTV2000
and Windows Media Player upon fail also reboots the system.
