I bought a Hauppauge 150 TV tuner card because I wanted the on-board
encoding. So the install went fine but when I watch TV the CPU usage
jumps from single digits to 95-100% and the computer is otherwise
pretty useless.

I had hoped the card was supposed to solve this problem. Could it be
another bottleneck somewhere? I have an AMD 1.3 chip on a ECS
motherboard with onboard audio, a 3DFX voodoo 3000, 512 MB ram, Win
2000 and 5 GB of free HDD.

Any advice would be appreciated

A PVR-150 card does encoding in hardware, so the process of recording
video should take next to zero CPU time. (All that's required is what
it takes to write the bitstream to disk)

What software are you using to "watch TV"?

What is your CPU usage when you play back an MPEG2 file that you had
recorded previously?

What process is taking up the CPU time? Assuming you're running
Windows, make sure you enable "Show kernel times" in the task manager to
make sure kernel/driver CPU usage isn't too high a percentage of your
total CPU usage.

I bet if you go into WinTV2000 and select Menu/Help/About/Status
it'll say Surface: Primary and not Surface: Overlay. This causes the
video stream to go through the CPU.

Get a video card that was made this century. Your Voodoo obviously
has overlay problems.

I checked and it says surface overlay. Don't know what that means
though or what to do.
