Product: ANYDVD HD Trial OS: Windows 7 Pro Player: Windows Media Player The video plays just fine, it simply has no sound. As far as I know I do not have Cinavia but I have the "Prevent player software from detecting Cinavia" checked in any event. I am using a USB headset and it is set to the default player in WMP and at the OS level. I can hear fine playing other things through WMP. What am I missing?
