G5 AGP + PCI Graphics performance issues

Can't Post

Hi there
For a show that uses four projectors to make a roughly 100 ft wide and 10 ft high panorama I will have to use a dual 1.8 Ghz G5 with AGP Graphic card slot. It has a Geforce 5200 in the AGP slot and two ATI Radeon 9200 Mac Edition cards installed in two of the PCI slots.
I am trying to play a single Quicktime movie 1920x192 pixels in size and encoded in Photo JPEG that I split on the four screens using a User Actor with four 3D projectors. I have already managed to run this quite well in my studio on a Mac Pro and I was hpoing to get the video to play at least around 15fps, but currently its framerate seems to be closer to 3,5fps.
We have tried to run it with the two ATI cards only but even then the playback doesn't exceed the 9fps.
The testfile I had sent to the theater to test the G5 can be found here:

Thanks for any help or suggestions
