Default TV-OUT image offset slightly on GeForce2, how can I adjust it??

I have TV-OUT over composite going to a standard TV (NTSC). The image is shifted a bit down and to the right. How can I shift it a bit up and to the left? Any ideas? Anyone have a good modeline and/or xorg.conf for this app for this card, I'm guessing it's a setting I'm too dim to figure out -- the docs are honestly confusing me.

(Wanted to try nvtv to see if it would help, but the app segfaults. )

The driver is 8774 on a Fedora Core 4 2.6.17-1.2142_FC4 kernel with a GeForce2 MX/MX 400 on AGP. I'm too cheap/poor to get a better card right now, regrettably.

(my second card is an ATI Rage, which I was going to use for TVOUT but it looked horrible -- washed out colours -- and I couldn't find a fix - can't get it to work with anything other than the stock ati driver or vesa because it's so old, so decided to use it for my regular desktop --- couldn't do dual head with just the GeForce2's outputs, regrettably, only seems to do TwinView with this kernel)

I tried xvidtune and it laughed at me. Said it couldn't handle the setup and generate the appropriate modeline.

Thanks in advance!!

My xorg.conf:

Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister@builder3)  Tue Aug  1 21:11:12 PDT 2006

# Xorg configuration created by system-config-display

In the end I just gave up. I wasn't able to find an answer. If you do, please post it!
