All commercial software players designed to play blu ray either have Cinavia detection at this point, or will have it soon. (DVDFab Player excepted) WinDVD 11 is one that I don't know about yet. It is the last one, in fact, that I haven't seen confirmation on.
If you are using WinDVD Pro 11, and have AnyDVD HD running in the background, and you have not experienced a Cinavia shutdown of the audio, then either one of two things is going on. Either your version of WinDVD doesn't have the Cinavia detection yet, or you simply haven't played a blu ray with Cinavia on it while running AnyDVD HD in the background.
If you are playing the original discs in WinDVD 11 without AnyDVD HD running, you'll never see the Cinavia message.
But some people need to run AnyDVD HD while playing blu ray movies, to get around region restrictions or to get around HDCP.
