XFX 7900GT and Adobe On Location

[orthogonal]

I am puzzled. I have installed Adobe CS3 on my machine and one component does not seem to work. That component is Adobe OnLocation CS3. It is a DV recording app based on the Serious Magic DV Rack. It uses video overlay to display video in the virtual instrumentation displayed on screen.
It does not function (No Video Overlay ) on my Desktop machine (XFX 7900GT) using one display 1920x1200. while the same application functions as intended on my Toshiba P25 Laptop with NVIDIA GeForce FX builtin Graphics card.

I have been through the driver removal and cleaning process and reinstalled the latest NVIDA driver on my Windows XP desktop. Still no video overlay. I have asked the question at XFX technical support and to get to this point I followed thier instructions. No luck so far...

Does anyone else know how to procede so I might correct the problem?
BTW Adobe says they fully support the Geforce 7600 and 8800 but not the 7900.
My main interest is HD Video Editing and Animation rather than games, do I just have the wrong video card or is there some other thing I am unaware of?
I would appreciate having the benefit of this groups knowledge.

It should work, but I would've got a 8800GT 512m for that res. I have never had a problem with my 7950GT AGP with any CS3 stuff, but I don't do video editing.

I have had the 7900 GT video card for a while So, there was not an 8800 GT when I bought it. I just bought the Adobe CS3 So far I have not gotten very far into the whole CS3 suite. I was just starting down the video capture road and ran into the OnLocation foible. I have not noticed anything that has not worked in Premiere Yet.

I did a quick search for "7900gt adobe on location" and couldn't find anything similar. I figure if it were an incompatibility someone else would probably have had it posted somewhere already. Can you try another card in that system to see if you have the same issue? Have you tried a few different driver versions? I would try these four versions. There are a couple old ones and a couple new ones to see if the program likes any of these better. Make sure you use driver cleaner pro in safe mode between each driver install.
