Hello,
If an increase in RAM sped things up a little, it indicates that the
CPU and not the graphic card is performing most of the tasks. Is the
graphics card a GeForce FX 5200 or a NVIDA GeForce FX 5200 because the
former is not Mac compliant? In any case, the graphics card is at the
low end of the series. There is a free program called OpenGL
Extensions Viewer that will let you see the OpenGL capabilities of
your system. OpenGL is at the core of the MacOS graphics.

To tell you one thing, Mac OS X leopard is really heavy on PPC
computer video cards if they are under 64MB VRAM, more or less the
video performance wouldn't be expected to be normal considering the
fact that the video card you have is original to your machine.
To clarify, after requests for clarification: The G5 is a single
processor 1.8GHz PowerMac. The video card has DVI and ADC on it, and
I'm running two monitors off it, an Apple ADC acrylic 20" and a
ViewSonic DVI 23" monitor. The card is a GEForce FX 5200 with 64MB
of VRAM.
I'm running the latest version of iMovie available for a G5. Audio
and visual were not syncing, and often skipping.
Videos on the Web improved with the added memory. Video on iTunes
improved but is still frame-by-frame jumpy.
I'm afraid I do not know the lingo that would allow me precise
communication.
All the advice about preparing a Mac for video is, I confess,
daunting. Thanks for the info. It sounds like video processing on a
G5 is as big a hassle as using Pro Tools on anything. Touchy
software, touchy computers.
I may simply not do video processing on it. I have an Intel Mac,
after all. Oh, well. Unplugging a computer from USB stuff and my LAN
seems like a crazy requirement, like a deliberate hobbling.
Something out of Harrison Bergeron.
But such is the cost of low-end computer use, eh?
