I had a question regarding the difference from AC3 to AC3 v2. I'm running a blueray movie in Divx Plus player version 8.2.2. I can use AC3 fine, but I needed to upgrade because I now have 7.1 surround. I can play the movie, but once I click on the AC3 v2 filter in the toolbar it doesn't open. If I then close the Divx Player the AC3 v2 settings page shows up, but as soon as I click on it it goes away. So basically I cannot change settings. I've tried using the OFFLINE mode, and I can changed them, but even after restart they don't work. Help please!
