I don't know it if has been posted yet, but with this drivers I have blue screen with nvlddmkm.sys when using the total media theatre 220.127.116.11. I use only to play blu ray either from a folder or with an image on daemon tools. It can start the movie but after a couple of minutes, maybe 10, maybe 30, I get this blue screen. try different movies, and the same. Didn't happen with the previous whql drivers. And only seems to happen with media theatre, didn't have any problems with other players, but I use this only for watching blu rays, so it is really annoying. I have a sli of titan. Don't know if any more info is needed.
