How to adjust X picture position? [SOLVED]

I have a home theatre PC hooked up to a PAL TV via the S-video port. I had to swap video cards recently to an old GeForce 2 MX400, and now the picture is slightly too high on my TV. That is, the top is off the screen, and there's a thin black border on the bottom. I'd like to shift everything down about 1 inch.

This is what I've tried:

Overscan setting in xorg.conf: apparently the MX400 doesn't support this. (Although in any case, I don't want to zoom the picture but rather move it.)
TV controls: bizarrely, my TV set lets me shift the picture horizontally but not vertically.
xvidtune: allowed me to change modeline numbers, some of which alleged to adjust the vertical position, but applying these made no noticeable difference.

Is there anything else I can do?

My modeline from xorg.conf:
Modeline "720x576x50" 26.80 720 752 848 880 576 588 593 605

My driver: nvidia-kernel-1.0.7676.

Er, not sure if that's a typo or if you are re-affirming that something I already tried won't work. But as per my first post, xvidtune did nothing for me.

For the record: I discovered the gtf command, which let me generate a better modeline.
