I currently would not suggest Windows 8.1 at all for Kodi. Cause we don't have any active developers that test DXVA on Windows 8.1 - All the development was done on Windows 7. Furthermore our implementation still bases on DX9, so you might experience real sever issues.

Edit: Most sane devs, just skipped Windows 8.1, cause it's not usable at all for anything else besides cooking coffee or something
