Cuda installed but application not recognising it

Question

I have a MacPro 3,1 with a NVIDIA GeForce GTX 560 2Gb graphic card. I've installed the Cuda driver and the necessary command line tools according to these instructions.
I have run the tests to see if installation was complete and got positive results. (See below.) When I open sorenson Squeezepro (9.0.3.11) and check the GPU preference panel I'm told Cuda drive is not installed on this computer.  Can anyone tell me if there is a sure fire way to check that Cuda is properly installed? If it is installed properly, why won't Squeeze recognise it/
Cheers and thanks for your help.

I'll try to help you, Lars. H. According to sorenson, your card does support CUDA
here are the drivers for snow Leopard
http://www.nvidia.com/object/MacOSX-CUDA-3.0.html
here are minimum requirements for cuda in Sorenson Squeeze
nvida CUDA driver 3.1 or better, GPU driver 19.5.9f02, whatever that means, 512 meg of video memory
and here you will find latest  CUDA
drivers for your nVidia card
http://www.nvidia.com/object/mac-driver-archive.html
see if that helps you out. CUDA 6.5.18 adds support for 10.9.5. You're supposed to be also able to download it by going to system prefences, then "other" , then CUDA, but I don't have that installed on my Pro, so I can't help you much more than this .

sorry-quick note here. If you go into Sorenson Squeeze, then Menu, then Preferences, then go to the GPU tab. your card should be recognized after you update the CUDA, then go to the GPU tab. Also, 10.9.5 may require that video memory for itself, leaving nothing for Sorenson Squeeze. You may have to buy a better video card, maybe
whew ! hopefully this fixes it for now
