You could just install the drivers and the card will function just fine. Not sure what ADM is or how good NVDVD player is though.
My Gainward, which I just got in to day, came with WinDVD 5, some Digital video editting software, and the driver/expertool CD. I just installed the Nvidia reference 61.77 drivers and Expertool 3.19 off Gainward's website. Seems to be working alright, although I've only run one loop of 3dm03.
