Cuvid works on the 64bit version of mpc-hc, as well as other players, just not 32bit mpc-hc. Unfortunately, svp doesn't support the 64 bit version. I hope there is a fix coming soon, not sure if I can live with the current quality...

Didn't work with the cuda drivers. Currently running the lasted NVIDIA 353.62 driver, and that doesn't support CUDA sad DXVA Video quality is no comparison to cuvid...anybody know of some other options, except for using an old nvidia video driver.

Changing the internal decoder to DXVA2 solved the problem for me, BUT Cuvid gave me MUCH BETTER video quality!!!!! So hopefully a new MPC-HC version will work with both Cuvid and Win10...
64 bit version of mpc-hc will work with cuvid, but I believe madvr only works with 32 bit...
