Hi - I have Rivatuner set up and working well - it's a great product thanks. My only problem is that it doesn't start to work after the first boot-up of the day. When it does cut in - after 30 mins or a re-boot (not quite sure which yet) then it seems to stay good even if I soft or hard re-boot. I have a 7800GT card and an Asus 8N Sli deluxe MB. Any insight would be very much appreciated. Thanks. ~Sticks~
