1. CUDA effects or non-CUDA effects? On what CPU? A slow CPU will not benefit as much as a fast CPU.
2. That is a nVidia driver limitation and does not impact on CUDA support. It will find Adobe Premiere Pro.exe
3. Update to 5.03
a. No, yes, encoding and some instances where hardware rendering is bypassed in favor of software rendering. Depends on the material and other circumstances.
b. 5.03 will enable it automatically. Check your project settigns.
Thank you for your quick response. I have Premiere Pro 5.0.3
AMD Phemon II, quad core, forget the clock, little more than a year old. I should have said that originally.
I am ignorant of what means CUDA effects. Please explain.
I resolved the "Mercury GPU not installed on this system" issue by setting everything in NVIDIA Control Panel back to defaults.
Would you mind commenting particularly on transcoding? Before I installed the GTX470, it took about 9 hours to transcode this project. After, about 6. However, the GPU % used is very low during transcoding, maybe 3%. Is this indicative of an issue or is it expected?
I read in the help about CUDA effects. I ran through a clip that uses Basic 3D and GPU % used was 5% maximum, which is better than 1 or 2%. I will continue to play with it and come back with additional questions.
Transcoding is still a potential issue.

Some effects are hardware accelerated, these are CUDA effects, because they use the CUDA engine on the video card. Others are not.
The GPU usage during transcoding is dependant on the source material and the export format. For instance if you start with HD (1920 x 1080) material and transcode to 720x576 SD PAL, the scaling is done by the video card (CUDA enabled). If there is no scaling during the transcode, then there is no assistance from the video card.
The faster the CPU and the memory, the more work can be done by the GPU, but if the CPU is slow, the video card is constantly waiting for the CPU. A Phenom II X4 is pretty slow, so the GPU is waiting for the CPU and will show low usage.
