[NVIDIA] GeForce 6150SE force 480i (1 Viewer)

This has been my first attempt at deploying MediaPortal, and let me say it's been bumpy at best. I finally have everything working and tuned how I want it, and it's time to attach it to the TV. The issue is I have an intergrated GeForce 6150SE and the card only has one output that I want to attach to the TV, it's a standard definition CRT so the output must be 480i. I installed the latest drives and nView, but I can not seem to tell it the attached display is a TV it just sees it as "Analog Display". I can add a custom resolution for 640x480 Progressive and it will run at this when I hit test, but I can't find a place to actually apply it permanently. I can also not get it to run 640x480 Interlaced, and when I try to test this it pops up a message "Attached device cannot support this". What I want to know is if am I overlooking some setting that allows me to force it to run at 480i regardless of what it thinks is attached? Or is there some kind of registry tweak or anything I can apply to force it to run at the resolution and scan pattern I need? Pretty much I just need to find a way to run a TV with the card in single display mode. The computer is attached to the TV right now, and I am making changes through VNC. Any advice would be appreciated.

Alright, so using PowerStrip I got the resolution to drop to 640x480 and run interlaced. I am so close to being up and running, right now the picture shows up on the TV but it can't quite lock correctly. I am pretty sure I have a setting slightly messed up in PowerStrip, can anyone offer advice on what front/back porch and sync width along with scan rate and pixel clock should be for NTSC 480i?
