Why an issue for us? Maybe an discussion, but definitly not an (Script) issue. We dont Support cuda/Nvidia.

Ah i was thinking that the script would also install the necessary things to support the hardware transcoding as everything seems to have everything installed on the client machine. Sorry if this not the case
