No OverScan with MSI Personal Cinema FX 5200 ???

[pe1chl]

I have an MSI Personal Cinema FX 5200, which is a card with GeForce FX 5200, NVIDIA tv-out chip, and video in and out on board (as well as a TV tuner).

I am using it in Linux and I am gradually configuring and testing the features. X on the VGA monitor works fine, as does the remote control. Yesterday I configured the TV-OUT feature as per the driver README, but it seems that the OverScan feature does not work. There is a 2cm black border around the picture on TV.

This is not what I expected from a "Personal Cinema" card, and also not what I expected after reading the README before buying:

o The "TVOverScan" option can be used to enable Overscan where
supported. Valid values are decimal values in the range 1.0 (which
means overscan as much as possible: make the image as large as
possible) and 0.0 (which means disable overscanning: make the image
as small as possible). Overscanning is disabled (0.0) by default.

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

As far as I understand, my card should be in the category that supports OverScan.

What can be wrong?
Is this a bug, or am I doing something wrong?

Options for the Device are:

Any help appreciated!
