Under audio output synchronization I use .30 sec delay for 3D movies with Powerdvd 17 and 18 and have never had a problem, but with Powerdvd 19 it will not stay selected. I have to reset it each time I play a movie. I am not sure why but if this problem was fixed I would have no problem upgrading but not until then.
