4346 != 4363. Versions before 4363 did not have vsync or
overscan support either.

The installer should have taken care of this for you but if
it was an earlier version, I think they used to handle it as
two separate packages.

GeForce 2? From the nVidia README:

    Overscan is currently only available on GeForce4 or newer GPUs
    with either NVIDIA or Conexant TV encoders.

For GeForce 2 you may wan to try nvtv which can control many
of the parameters for most GeForce 2 cards.
