Thanks for your reply, i've literally just finished using the kernel helper for 6.9.1 stable.
I think I know where I was going wrong, a long time ago I was using the linuxserver.io unraid Nvidia, and Unraid DVB Plugins. They overwrote each other not your drivers.
Re-looking just now I see there are two plugins I need in your Repo, Nvidia Driver, and DVB Driver.
Thanks for your efforts! I'll try them next build rather than the Kernel Builder. p.s the Kernel Builder has been amazing.
